When I create an event and then I want to change the calendar to which it was attached (e.g. "personal" -> "work"), I am unable to do it in Windows. In Android app it is possible, but in Windows I have to delete this event and create a new one with the proper calendar attached (or edit this event on my Android phone...).

Grew,blue,green what was the color for my important meetings? Lets add names on the colors so you can call for example:

green = meeting red = birthday of my girlfriend etc.................

If you create a repeating event, then attempt to edit you can only edit the individual appointment not the series.

More colours to choosewould be nice,cause ts to less colours once in a while
