Falta data no calendário no decorrer dos dias. 

Unfortunately the Caldav synchronisation does not work with horde.

It says no "sync token" support.

Being able to show a location-based (preferably a set location that can be changed for any given day (for example when working away or on holiday) rather than a live location) sunrise and sunset time on the calendar would be amazing.

It seems that as soon as an entry is made or one edited, the App immediately goes into Sync mode.

This happens regardless of what the App's Sync settings are!

It would be better If there was a way to turn this off, as I have found that when making lots of or editing many, I start getting iCloud Sync error messages due to too frequent syncing. 

Can we have an option to display the Location field in the Calendar view please? Particularly the Daily & Weekly views.

Off line Outlook within MS Office on my PC should be able to seamlessly synchronise with my Android phone without having to give all of my information to Google through their Calendar app(s)

I suggest to implement the Ical link in order to shere all the calendars of onecalendar with outlook. I use outlook for job and should be very helpful see all my appointments in the outlook calendar in order to avoid conflict. I can't directly share my calendars to outlook because of the impossibility to share through Ical the family calendar of Google (that it's ridiculous but this it's how it works)

It would be great to have the option to delete future events from a series. Meaning to keep the series till now, but to delete the events that didnt start yet

Is there plans for a web version?

When trying to edit calendar event. I cant seem to be able to change the calender the event is under. Would be great if this could be possible. 

I would like to request more appointments shown in the full screen (6x5) month widget. Currently only 4 are allowed but there's space for collapsing around the text of the appointment. I've attached 2 screenshots, one from this widget where the appointment height is tall with space around the text, and Google Calendar, where the appointment height is 1 line of text high and 6 appointments can fit. I would love to see 6+ appointments or however many can fit when the height is collapsed.

Is there a possibility to sync the One calendar application on my Android phone with my tesla model 3 calender application?

That would be awesome.

Build it dude

Can you add a color per category that we could choose and predefine according to the appointmen. For example, choose in blue for medical appointment, red for sports appointment, green for the restaurants etc

thank you

I am using this as a wall calendar for my family and would love the option to make the font larger in the week view

Not exactly a calendar, but closely related: support for reminders (in my case iCloud reminders)
