There are just a few colors for optional.More colors would improve the classiefiction.

Upcoming events in Lock Screen would be perfect 

would like the ability for the start day to be other days eg. Thurs.  especially when I work thursday to wed as work week

When in weekview there are only 6 lines visible. If you have more events, there is no indication that you must scroll to see more

I've been in touch with support, and I've been asked to post it as a feature (when it's clearly a bug).

You are not able to change the time for Gmail events, when trying to edit the series.  It works fine for individual occurrences, but not the series.

Can you add Mapquest to navigation options?

It's good to run the program, but I want you to add a widget function that you can see directly on your desktop to Windows 10 like mobile

Please make a widget of the week view, the agenda or the monthly view is not nearly as good.

Could you please add the possibility to minimize the area for full day events or set it to a maximum size for this area and make it scrollable. We have that much full day events, that it take more than the half of the screen.

Hello,

i have my collegue calendar as well as mine. When i add him to an apointment, I see mine and his apointment on the same time, same text (diferent color). It would be nice to hide his apointment when i have the same with his name.

A visual highlighting of all day events compare to normal events in the overviews would be very helpful. 

Does OneCalendar MacOS has a feature "Go To Date"? To jump to a specific date?

If not, that would be a much appriciated feature to have.

When appts are made on pc, they show up in the color according to OneCalendar settings. But I want to color code by type of events/meetings. But when the color is changed, all attendees receive a change notification.  All that changed was the color for my own organization. Attendees do not need to receive a change notification.  Please stop or give us options to choose. 

Entering location for event could do with suggestions to select from as you type.  See Google Calendar and Readdle Calendars5.  Very useful.
