+1 - One of the key features for calendar. Loved it in Google. Please add.

I'd add, allow different types of tasks with different color codes for categories that the user can create and customize. For example, pink for personal, green for finance, red for critical. Allow an app or integration with calendar app where things get checked off as they get done.

This is the reason my SO doesn't want to move to Proton Calendar.

I use Todoist, it is my favourite todo list application. I would be very happy if they would allow 2-way integration like they have between Todoist and Google Calendar. This lack of integration is probably the biggest road block for me to transition away from gmail / Microsoft and onto the Proton platform.

This would be really useful for productivity.

Not terribly important. I use Google Tasks and like its design and function.

The long, long delay in implementing a core feature of any calendar app like this is making it very frustrating to try and move over to Proton completely.

This is a really important feature that deserves more attention.

The last feature that will let me completely ditch my gmail account. I can look at individual reminder apps, but what a hassle! This should be part of any calendar app.

Posted in 2015, under review since 2022.

a must-have feature still unavailable in Proton.

A simple checklist of "Tasks" as an additional option for the right-most panel in Proton Mail would suffice.

Agreed, it cannot be called a "suite" without having one. At this point, it is unacceptable.

This seems a basic “must have” for a business calendar. The calendar is useless to me without tasks.

We are close to celebrate the 10 years... Proton, where are you?

CRITICALLL!!! POSTED IN 2015???

Simple To-Do-list where you can sort the tasks by importance

I am getting a bit annoyed having to set 0 minute events. I would love a reminder function

As a business user of Proton Calendar it's hard to support development of a new feature like tasks/todos when basic Calendar features are still missing, like:

Edit instance of a Recurring Event
https://protonmail.uservoice.com/forums/932842-proton-calendar/suggestions/43452336-edit-single-instance-of-a-recurring-event

and

Create Calendar Event from Email
https://protonmail.uservoice.com/forums/932842-proton-calendar/suggestions/45812551-create-calendar-event-from-email

If I was working for Proton and thinking strategically, I'd want to be going after the business/enterprise market as well as being the privacy-focused Gmail replacement for individual users.

Without basic features like the above, adding tasks/todos right now is not going to help IMHO. To me, Calendar just simply does not seem feature complete enough yet for serious business use (or personal use if you rely a lot on your Calendar).

I note that there are a lot of people in the comments saying that Tasks are "critical" for them to be able to move away from Outlook/Gmail etc. I suggest that only when those people actually migrate away from their existing calendar system will they discover other things like the above that are missing. These small details are equally as critical for adoption but far less obvious until you actually start trying to use it. I hope the Proton team take this into account when assessing which features to work on.
