Ability to sync with Outlook categories and sort by categories within the app.

In Omnifocus, I can set a "start date", which is the date that the task is available to be worked on. We can choose the view (for example "all future tasks", "all visible or available tasks"). With this feature it is possible to better organize the future due dates and tasks, hiding the tasks of a far future. It would be welcome in MS ToDo.

Add task from browser with support for both choosing list on each adding or/and set a standard list where entry is added by default. It would be a nice feature to show standard adding-list, and last “used” list in top position and then all lists available beneath.

Having the ability to set a due date or reminder for an individual subtask.

So we can drag and drop tasks to other lists like Trello

Import from google keep, 24me, Evernote, ticktick, reminds..

This is a must given that this is a Microsoft product

I would love if I could color code the parts of my list so I can easily look at the parts of the list categorically at a glance! I absolutely love Microsoft To Do!

Ability to backup/export all lists. Either to CSV/PDF/Excel and/or a backup file so that we can restore in the event of something going wrong with my lists or the Exchange server that hosts the lists. We need some level of assurance that our precious lists are safe!

Accidently have check off some task due to its location. An undo botton would resolve accidently check off task.

The input tag list is displayed and I need to select the existing tag and input it when I enter a todo.
Also, when searching, it would be nice to have a function to search by various combinations of tags and text.

Specifically shopping list, but also add reminders

Numbers, bullets, bold, color, font, hyperlinks, images, files, checklist..like the way Trello allows.

This was a really handy feature in Wunderlist - the ability to copy/paste both lists and tasks...

I had a number of template lists which I could copy if I needed. For instance, a generic list of holiday items to pack which would be copied/pasted each time I went on a new trip.

Thankfully - the excellent integration with Outlook means I can do this at the Outlook end, and it'll be replicated in To-Do! :)

I would like ifttt support or similar. I would like to be use this to input tasks using Siri

I find it a little annoying I can't see all my tasks from multiple accounts. It would be good to see all tasks with a tag to say which account that task is linked to. I sometimes add tasks to my personal account when I meant to add it to my work account because I have forgotten which account I'm looking at.

It would be amazing to have to-do lists per project, where in one single view a user can see it's own tasks disregarding the project (overview on top of projects). This would also benefit the follow-up of assigned tasks within a project by for example a project manager.

So that I can decide how much time I should spend on it and work towards that

Please let us choose a custom background and add more backgrounds and colors for the theme options also.
