At the moment I am using the reminder app on my iphone. It woud be great if there was a simple reminder Proton app so that I would be less dependend on icloud.

Yes, suite needs to add task management (lists, habit tracker). Look at LunaTask

Critical companion to the calendar. Must have to complete the experience.

Critical companion

My wife and on the Duo plan would utilize this to sync with the calendar would be amazing

Having a simple to-do feature in Proton Mail would be a tremendous improvement and is a feature I would love to have available. I use tools like ClickUp for task and project management, but I don't need as heavy a tool for personal things. I'd especially like to see email integrated with it. For example, if there is something I need to do in response to an email, I would want to create a task and attach a copy of the message to it.

Super productivity would be a nice addition to the Proton suite. It has integration with calendars and is open source.

Other email/calendar services have a means to store ToDos, usually integrated into calendar functionality (like including due dates and such, with calendar-related alerts.)

I am a big fan of Todo lists, but due to de-googling my life, Im currently using manual todo lists on my eInk tablet. It works, but I'd rather have it in digital form that is much easier to manage, shift tasks around, have alerts for upcoming due dates, etc.

Honestly, I think this basic feature would be implemented prior to launching into competition with google docs/etc. But I also am looking forward to competing SECURE and PRIVATE solutions to Google Docs as well.

Thanks

maybe have integrate with Proton Notes, notion competitor even? idk

This is a duplicated idea of https://protonmail.uservoice.com/forums/932842-proton-calendar/suggestions/7158378-proton-tasks-to-do-list

This is a must! I've really been enjoying the Proton suite on Linux, but the main thing missing is still having to rely on Microsoft's To Do app for scheduling and planning my day. I use it to track my upcoming bills, subscriptions, shopping lists, appointments, and various other lists to keep myself organized, yet the Proton Calendar app is insufficient in this area. The Calendar app lacks the functionality to create, group, and organize itemized lists where items can be ticked off once they're completed.

Absolutely, I saw in the Proton Calendar portion many different threads asking for this. I also saw people asking for better time block scheduling. Scheduling a todo task to automatically copy to the next day if not checked. And another great feature would be able to drag and drop items on the calendar to new dates.

I want the UI to be easy enough I can write down todos in the calendar app (and drive) while running without having to stop it's so good.

These would be one of the most important features.

At first I thought this may be out of scope for Proton, and perhaps it is. But I have searched for years for something like Todoist but open source and end to end encrypted. There are many apps in this space, but I mention Todoist because it has the ability to function as a project management app (for a freelancer or small team) while still being usable for day to day tasks. Take that functionality, give it Proton privacy, and integrate it with Drive, Calendar, Mail, Standard Notes, etc, and it would be a powerhouse.

To be honest: I will not continue to use proton (having tested it for a few weeks now) only because of this. I do not understand, how you can concentrate expanding your product suite with VPN and Pass (next to many good alternatives) while not creating a todo-app and perfecting the mail-calendar-todo-combination on all devices.

I would only suggest taking Google Tasks as a model with the "all-lists-on-one-board"-style. There should be labels too (in addition to categories = lists). And there should be a function to be reminded on a specific date.

If I get an E-Mail, I should be able to make a task or a calendar entry with one click (maybe a few more but only in cases I do not what e.g. the standard-todo-category set by myself prior).
