At least on my phone Galaxy S24 Ultra and One UI 7 the reminders are easy to miss. It would be awesome if they could be more similar to an clock alarm that rings and that I have to dismiss manually. I just missed a meeting while the phone is just 30 centimeters in front of my face.

A lot of people dislike the Proton Calendar app; it is buggy on both the Android and iOS platforms. This calendar is already really good, and adding support for Proton Calendar would make this calendar app even better.

Is it possible to add other navigation choices such as Sygic or Tomtom. Nice app

Either allow to create a category (mapped to the CATEGORIES: field in CalDAV)

or allow to label the color that could be assigned for an appointment (this could be an enhancement for the Customizable Colors functionality)

Would like One Calendar to synch with Samsung calendar

If you add a date that you have added before e.g. "church" or "tennis" the times and color code of the old event should be transfered as well. 

It's a shift worker thing, the shifts have names, 1 - 8, and if I add a 1 to the calendar I want it to automatically insert the the (last entered) time, 05.30-14.00 and the color which has been associated to that date. Google calendar can do it.

Right now OneCalendar only shows contact birthdays? Google contacts app supports multiple dates for contact (for example, spouse's birthday). It would be great if OneCalendar showed them and worked with them just like it works with birthday dates.

I propose to add the possibility off adding calendar in shared Mailsboxes to OneCalendar. We have different calednars in Shared Mailboxes.

Sync error showing.

I would like to have a visual difference between confirmed and tentative events, either through some sort of dimming, an icon, or anything else that would help differentiate status of the events.

In my work calendar I have "Lunch" and "Focus Time" - this is for other people's benefit so they don't disturb me during this time, but isn't something I need to see, it would be great if there was an 'Ignore List' with title matching that would simply not display those events on the widget.

The reminder for an event disappears after a short time, at the scheduled end time of the event, in short-term events the reminder is not seen and you forget about the event. Could an option be added in settings so that the reminder does not disappear until the user takes action on it (Edit it, postpone it or deactivate it) ?. Thanks.

allow repeat to do "every other". ie, every other week, every other day
