Wunderlist was a popular task management application that allowed users to create and organize to-do lists. However, Microsoft acquired the app and gradually retired it in favor of their own task management app called Microsoft To Do
Microsoft encouraged Wunderlist users to transition to Microsoft To Do, and they provided tools to assist with the migration of tasks and lists from Wunderlist to the new app.
You can read the article "How to connect Microsoft To Do with Trello" here.
Pleexy creates tasks and sub-tasks in your Wunderlist from cards and checklist items in Trello. Pleexy can synchronize checklists and automatically move Trello cards to the “complete” list you specify when you complete tasks in your Wunderlist.
After you connect Trello as a source service, customize Pleexy’s settings to integrate Trello and Wunderlist exactly the way you want. First, navigate to the page where you can change settings:
From the Pleexy dashboard, inside the Trello card, click Details.
Click Edit settings.
On this page, you can customize the connection's name. You can also adjust the settings for Source, Destination, Tasks, Actions, and Checklists. Let’s walk through your options for each.
Source settings
Source settings let you configure how Pleexy searches for cards in Trello. Use the drop-down menus to select which Trello boards and lists Pleexy will search for cards. You can also specify whether Pleexy will take Trello cards assigned only to you or cards assigned to anyone.
Pleexy combines your settings for these three filters. For example, if you choose the board Alpha Sprint, select the lists Queue and In Progress, and select tasks assigned only to you, Pleexy will search for cards that meet all three requirements:
On the board Alpha Sprint
+ Located in lists Queue and In Progress
+ Assigned only to you
Destination settings
Destination settings define how Pleexy creates tasks in your Wunderlist. You have two destination options:
Put all tasks in one project: Create tasks from all Trello boards in the same Wunderlist project. Click the drop-down menu to select the Wunderlist project to use.
Note: If you want Pleexy to create tasks in a new Wunderlist project, log in to your Wunderlist and create the new project there. Back in your Pleexy settings, in the project drop-down menu, click Refresh to update the list of projects.
Use an individual project for each board: Create tasks from each Trello board in a different Wunderlist project. Click the drop-down menu to select the root Wunderlist project to use. Pleexy will create individual projects within the root project you select for the tasks from each Trello board.
Note: If a project with the same name already exists in the root project you select, Pleexy will use it instead of creating a new project. This way, Pleexy can combine tasks from different source services in the same project. For example, Pleexy will create tasks from a “Development” notebook in Evernote and a “Development” board in Trello in a single root project.
Task settings
In the Task settings, you can specify how Pleexy creates, names, and synchronizes tasks and task attributes.
Under Task title template, use macros to customize how Pleexy names your tasks. For Trello integrations, three elements are available for task names: {board}, {list}, and {card}.
As you change your task title template, Pleexy shows how your changes will look in a live example under the template field. You can combine the macro elements however you want, as long as you get the formatting correct. Here are some ideas:
{card} from {list} in the {board} board
{board} - {list}: {card}
Note: If you manually edit a task title in Wunderlist, Pleexy won’t update or change your edited title.
Under Synchronize due date, you have four options for how Pleexy handles your changes to task due dates:
From Trello to Wunderlist only: when due date changes in Trello, change it in Wunderlist
Both in Trello and Wunderlist: when due date changes in one place, change it in the other
From Wunderlist to Trello only: when due date changes in Wunderlist, change it in Trello
Do not sync: do not synchronize due dates between Wunderlist and Trello
You can also toggle-on Add card description as task's comment in Wunderlist if you want Pleexy to show Trello card descriptions in task comments in Wunderlist.
Finally, you can customize which Trello lists Pleexy should consider completed:
Do not track completeness of cards: Pleexy will not assume that any cards are completed
Last on the board: Pleexy will assume that cards in the last list of a board are completed
If you selected specific boards for Pleexy to search in your Source settings, you have the option to specify which list Pleexy will consider completed for each board
Action settings
Action settings let you control what Pleexy will do when you change, complete, or delete cards or tasks in Trello or Wunderlist—both sides of the integration!
First, tell Pleexy what should happen in Wunderlist when you delete a card in Trello. Click the drop-down to select one option:
Delete corresponding task: Pleexy will delete the corresponding task in Wunderlist
Do not touch task: Pleexy will leave the corresponding task in Wunderlist
Second, tell Pleexy what should happen in Wunderlist when you complete a card in Trello. Click the drop-down to select one option:
Complete task: Pleexy will complete the corresponding task in Wunderlist
Do not touch task: Pleexy will leave the corresponding task in Wunderlist
Note: If you selected Do not track completeness of cards in your Destination settings, you will not have this option.
Third, specify what should happen in Trello when you complete a task in Wunderlist. Click the drop-down menu to select one option:
Complete card: Pleexy will complete the corresponding card in Trello
Do not touch card: Pleexy will leave the corresponding card in Trello
Note: If you selected Do not track completeness of cards in your Destination settings, you will not have this option.
Checklist settings
For Trello integrations, you can also customize settings for Trello checklists.
Your first option is whether Pleexy should create sub-tasks for checklist items. Toggle this option on if you want Pleexy to group all checklist items from one Trello card under one task. If you toggle this option off, you can choose whether Pleexy should delete checklist items for mapped cards. Toggling this option off also removes the other options for checklist settings.
Next, you have checklist-specific Task title template settings. These follow the same rules as the general task title macros, but you can include up to five elements in task names for checklists: {item}, {checklist}, {card}, {list}, and {board}.
Next, you’ll see three more customization options for how Pleexy should handle deleted and completed checklist items.
First, tell Pleexy what should happen in Wunderlist when you delete a checklist item in Trello. Click the drop-down to select one option:
Delete corresponding task: Pleexy will delete the corresponding task in Wunderlist
Do not touch task: Pleexy will leave the corresponding task in Wunderlist
Second, specify what should happen in Wunderlist when you complete a checklist item in Trello. Click the drop-down menu to select one option:
Complete task: Pleexy should mark the corresponding task as complete in Wunderlist
Do not touch task: Pleexy should not mark the corresponding task as complete in Wunderlist
Third, specify what should happen in Trello when you complete a checklist task in Wunderlist. Click the drop-down menu to select one option:
Complete item: Pleexy should mark the corresponding item as complete in Trello
Do not touch item: Pleexy should not mark the corresponding item as complete in Trello
Those are your options for integrating Trello with your Wunderlist! Don’t forget to scroll down and click Save changes when you’re finished customizing.
