I'd like to move 100% away from Google Calendar and the task list and "sticky" notes are the only things really making me stay there.

I'd really appreciate the ability to add To Dos to Proton Calendar, with features such as a Due By date where the to-do item would automatically appear as an all-day event on that date in the calendar...and if the due date was passed with the item not yet marked as 100% complete the item would continue to appear as an all-day event for the current date highlighted as 'Past Due', until marked as 100% complete (or deleted). Two of the best PIMs I've used were DateBk5 on my Sony CLIÉ (PalmOS) device and (IBM) Lotus Organizer on Windows...both of which had many useful productivity and usability features in their calendar and to-do functions that are sadly missing from today's offerings. It would be terrific if Proton could include many of these capabilities into Proton Calendar.

Very useful at least tasks with the following basic features:
- chance to set a "completed" state
- customizable repetition
- a listing view of all the tasks ordered in different ways (name, due date,...)

The only reason I don't currently use Proton Calendar and keep using Google Calendar is because it does not support creation of tasks like Google Calendar. If I could, I'd completely switch

An integrated task manager would be super helpful, to complement mail, calendar, and storage. Tasks can arise from all of these, involve all of these, or lead to all of these, so a task manager - for the task-driven among us - could almost function as the center of a hub of capabilities. Starting with a task, it would be so helpful to be able to calendar it, lead to generating necessary emails, storing or accessing required files, etc. To-do checklists, breaking tasks into subtasks, recurring tasks, prioritizing tasks, etc. would really be a great addition to such a great suite of tools.

This is what is stopping me from switching completely from Google to Proton

This is the only thing that prevents me from leaving Google Cal and and starting to use Proton Calendar

And please keep past tasks in full bright color until they are checked off.

Microsoft, Google and Apple have separate apps for tasks/to-do lists and I feel like this is the way to go for Proton as well. Add yet another app to the portfolio - Proton Tasks, Proton To-Do, Proton Reminders or something along that line.

Yes please. Use case: As a person with ADHD, an integrated task and reminder feature would be incredibly welcome. This is helpful for creating a centralized experience across work and personal. Notes would a bonus and a task list that would allow a bit more detail than just the task title.

This is super-useful.

Notes and checklists would be nice and to be able to assign or share

This would be huge for me!

I would also suggest the possibility to have notes

This or reminders in Calendar would meet my needs.

Agree, it's the main reason I cannot move away from Informant. The features in Proton Calendar are just not there without losing functionality like to ToDo appearing in my agenda view of my calendar that I am used to. I would add Notes functionality to this as well

Tasks, To-Dos, and Reminders please! along the lines of Tasks.org.
With open protocols and multiple sync options like DAVx⁵, CalDAV, EteSync, or DecSync CC

I would definitly die for such a simple solution as Bullet Journal/Bullet list like Workflowy which is definitely a theft at it's prices...

Including it in your offers would be Ace!

Greatly needed!

Build out your own To-Do / Task app instead of trying to integrate with Todoist or any other non e2ee apps. The biggest reason people migrate over to services like Proton is to protect our data from privacy abusing big tech. Todoist can see everything you do! So having in-house e2ee task / to-do app that integrates with calendar will see a massive wave of new users subscrive to Proton.. dont forget to give users color options in (free) calendar app. Skiff already offers this so get smart Proton !! Build your user base further by offering the best value !!
