Feature Ideas

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

This is useful when you only know that you must finish a project by a specific date, but you don't want to waste time assigning dates to each of the tasks, so that you can have some flexibility to choose the tasks that suit you best.

The workweek mostly starts with Monday and all the calendar apps are often adapted. I keep making mistakes while adding dates to tasks because I cant change week start from Sunday to Monday

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.

Allow users to manage labels (e.g., deleting, renaming) to give them functional use.

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

Provide an underline formatting button (on mobile & shortcut on desktop) - maybe instead of the strikethrough formatting button?

When a task has content (for example subtasts) allow the users to drag the task to the sidebar to convert it to a list. Also allow lists to be dragged inside another list to convert it to a task with content. (My first thought was to allow lists in lists, but tasks are already lists so in Superlist this may make more sense.)

by default, superlist takes Sunday as the first day of the week. It should be configurable by the user because regional configuration don't always work that way

The ability to merge duplicate tasks would help us retain information from both tasks when we accidentally create more than one task for the same topic. An auto-merge suggestion feature would be pretty nifty as well.

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.

Seamless integration of the calendar to enter tasks directly at a specific time would greatly assist in planning the day. If you want to schedule a task, another window with the calendar could open on the right. In this window, you should also be able to directly schedule the required time by reducing or enlarging the task.

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.

Allow users to quickly duplicate tasks and lists to save time when creating new items based on existing ones.
