Feature Ideas

I find it useful to see my tasks spread in a calendar, especially in weekly view, so I can make sure I have a healthy workload in my hands each day.

Set optional start and end dates on tasks to make planning easier.

The Today view is great, but Week view would be helpful to navigate through the week and not get lost in the detail of one task.

Select multiple tasks to edit or move all at once.

For example: "Repeat after completion" "Repeat X days, weeks, months... after previous item is checked off". For bills to send or training items it makes sense to create a new tasks when previous is completed with a parametre.

Enable Windows users to manage lists and tasks with a dedicated desktop app.

Archive lists to keep your space organized but access them at any point in time.

Feature request for mobile: Swipe actions on list elements Swipe actions - at least two: one swipe action should be to open a quick action menu for the selected task (where you can delete it, move it to inbox or parent task, change element settings, etc) the other swipe action should be freely customizable to the user's liking (possible actions: complete, delete, move to another list, change date, change assignee, change label, no action, ...) Swipe mechanics: swipe right swipe left (maybe) swipe far right (swipe action #3) (maybe) swipe far left (swipe action #4) Imho this swipe mechanic should replace the long press mechanic which currently opens a quick action menu. Todoist & TickTick (other apps probably too) also have this quick swipe mechanic, it's great! :)

Another highly useful feature - voice input into Siri right into the inbox. Omnifocus has the best implementation, Things isn't bad. Here is how it should work: use your iPhone to say something like: "Remind me to go to the Drycleaners tomorrow" A task immediately goes right into your inbox: "Go to Drycleaners" with a due date of tomorrow.

Allow users to mark a task as canceled / not completed to indicate that the task will not be worked on while preserving its details.

Allow users to restore lists and tasks that might have been accidentally deleted.

Being able to integrate YouTube videos directly into the app (without opening Safari) would be an asset.

Add Apple Pencil integration on iPad (and other pens on other tablet and laptop devices) for quick note taking.

undo / redo buttons for the text editor - but maybe also for list actions (creation/deletion/moving of elements etc)

Many recurring tasks are used as a reminder to complete a "habit." It would be great to see a history of completions, whether in the form of a "streak" or a calendar heat map in the detail view.
