Ability to turn notes into sticky notes that can be linked to desktop (such as Notezilla)

I use Wunderlist and I know the ability to share tasks is coming to To-Do but the one drawback with Wunderlist was not being able to assign a task to more than one person.

There are often similar Tasks or Workflows in business. So it would be nice to have an option to define Templates for tasks/Workflows (Task with sub-tasks and dynamic reminders like 2-weeks after start). This would allow the user to manage internal processes with the todo-list. Maybe it's also possible to start a workflow by sending a mail to the todo-list and giving some attributes in the subject to initiate the details of the task/workflow.

Outlook tasks have 3 priority levels and this app only has two.

can change task font and size

Get notifications for incoming tasks and ability to mark them as completed from the notification.

Let's configure ringtones individualy for lists

Import specific music
Configure the volume etc

Persistent Notifications/Reminder option!

It would be really useful to have an option that when a reminder is displayed, it keeps showing on the home screen until it's actioned or snoozed, like you can in iOS native reminders. This makes it much better as you are constantly reminded until you manually mark the reminder as complete. This would be so helpful and I've been waiting for this in Wunderlist for years. Please implement this if you can!

Please add a “today” smart list of things due today plus a weekly view

Or let Wunderlist continue

Please allow separate sorting of the completed list - completed should be able to display by date completed

Add the ability to tag tasks with priorities important/not important & urgent/not urgent (cf https://en.wikipedia.org/wiki/Timemanagement#TheEisenhower_Method)
Add a cross lists view displaying the tasks in the 2x2 matrix

Completed items to be excluded from searches and ability to view and search just completed items

Choose a list on your watch, and check off items as you go on your watch!

I have multiple work accounts and a personal account. It would be good to have all these actions in a single To Do app - with the ability to see them ordered by account, with additional items added being integrated to the appropriate source account.
Is this likely anytime soon?

It would be great if we could add our own custom priority list to be used for a list.

Default Due Dates and Reminders for new tasks

Provide option to share a Group created with other users. Currently have to share per list in a Group Manually and have to track if missed to share any list in a group with others.
I would be fantastic to have sharing options like Parent/Child settings. Like Child List inherent sharing options from Group Parent or can have unique permissions.

Allow your completed ToDos to be kept, logged, and searchable. This would allow people to have a searchable log of the tasks and it's notes they've completed if needed. This data can be linked into a user's OneDrive account and accessible with other Microsoft office tools.
