Often I have tasks to do within the day and I don't necessarily want to delete them from the calendar once they're done in order to keep track of the day they were executed nor do I want to keep getting notifications for them as they are done. Therefore I think it would be amazing to have the possibility to check the tasks in proton calendar (like in a to-do list) so that we don't get notifications for them anymore but they keep appearing as executed in the calendar. I wouldn't force all events of the calendar to be like that as maybe other people don't want this feature, but having the option to use it would be really practical!

One could even imagine a feature which would propose to postpone the task to the next day if it could not be performed the day it was planned (happens a lot to me sadly and I guess I am not the only one).

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

This is the only thing keeping me stuck to the big G. Mail, Calendar, Tasks are the triumvirate.

This would be huge for me!

I would also suggest the possibility to have notes

This or reminders in Calendar would meet my needs.

I really want this feature. I really miss it from Google Calendar. I need to be able to set simple reminders, with notifications when they are due. I also need reoccurrence features. As a software dev, this seems like it should be a pretty easy feature to build on top of the existing events in Proton Calendar.

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!

I registered here solely to pass this message!

The only one thing that keeps me from getting off of google services, completelly ...

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 !!

To fully de-g00gle myself this would be one of the last things. In fact I use "Todoist App" and I would love an integration with Proton Calendar. I prefer to use a professional app for task management and having it synced to Proton platform.

As @ohoh mentioned markdown is the gateway to cross-platform and easy actions management.

This is super-useful.
Also, the task/todo list has to allow sharing read/write with other proton users, and read only with other email addresses (better if write was allowed, but not a requirement)

We need this !

This is the last feature I require to be completely "free" from Google.

PLEASE ADD THIS

Agree with the comments below! This is a high priority! Already switched from Google to Proton and this is one of the key things missing!

Would love it!
