The app should have the possibility of creating multiple todo lists (personal, work, shopping, etc)
It should have a view to allow users to see what tasks are due on a particular day.

This would be huge! this is the biggest thing that is preventing me from switching fully over.

Proton Tasks could be a new task management app, or have it built into Proton Calendar.
Many features, like sub-tasks, date & time, priority, images, repeating tasks, etc.

Would also like to see, something with same features like Microsoft To Do

I use Google Tasks and would love to switch. It would be important to have recurring events, and reliable notifications on mobile.

Guys! Are you serious? Come on, those things are essential! Can you FINALLY implement tasks and to-do lists?

Trying to get away from Google as a whole, this would really help! To do lists and tasks are essential for an efficient calendar app in my opinion! Please add this! Based on your roadmap, you guys have been promising Tasks / To-DO Lists for way too long!

I think this is a great idea but I think it should be integrated in with the calendar app. Much like how Google does it with Tasks (which used to be reminders).

I would love to be able to use Proton calendar as completely as I did with Google. Most important was the ability to create a Task, and then break it down to the component parts with nested subtasks:
Task/due date/desc
Subtask/due date/desc
Subtask/due date/desc
I am an artist working on commissions; many projects going at once, all with critical deadlines. It's impossible to keep it all in my head, or use multiple apps with lists, or post-it notes!
Thank you for considering.

Having some todo list style capability would be awesome as well. It could also work in Pass notes, but a checklist/todo is probably better suited to a reminder/calendar than a secure note.

Create a reminders app equivalent to apples reminders app. With the same features and connectivity.

Sounds like caldav. Caldav
With encryption would be awesome!

Definitly a must. I would add that it should be accessible via the proton mail app and link to proton calendar app

Yes, I was going to write my own suggestion about this, but I'll add it in the comments to the other "to-do" suggestions. I am not partial to Microsoft or Microsoft ToDo, but I would like a great Goals/Priorities organizer that would suit all my needs. I've spent days looking for one and only partial luck. Proton calendar, Proton Pass, Proton email, Proton Drive all help me do a little of this. I'm thinking something that is highly customizable would help the most users with their various needs. For me: 1) All areas can use drag & drop to rearrange order 2) All areas can be edited for titles, list entries, colors, etc. 3)Repeat available 4)Move to another list available (advance) 5) Multiple lists available, like 20 or more (groceries, books, etc.) 6) I like the Eisenhower Matrix, but I want subsections for areas of life and sub-subsections to break down projects. 7) I also like "1 3 5 To Do List" and wish I could combine all this. 8) Bonus: Add times and dates, reminders. 9) Bonus: mission statement prominently displayed on one or more Proton apps. 10) Dream bonus: just being able to hover over a TUUDO, Microsoft, Google, or other calendar entry or event in an email and have it added to Proton calendar. Overview: I could imagine toggling between an A) Eisenhower Matrix, B) Proton Calendar (maybe some of this could be part of the calendar), C) Various lists for groceries, books, cleaning, yadda yadda (maybe some of this could be part of proton pass notes) D) a 1-3-5 today, tomorrow, someday (widget? - I could see this as part of Proton calendar). I know this is a lot. Thanks for considering.

Please make proton to do lists in calander!!!

@ Christopher Bates: it is not marked as planned, just as "checked/considered".

Request is now 8 years old and still nothing ???
Together with same request in another topic nearly 2500 votes!

This is the single one feature missing that I require to switch from GMAIL. It's how I organize my days...
