Hard to make suggestions as I'm starting to get used to the settings...
Meanwhile, I think I found a little bug: I had four appointments for tomorrow and using the left side panel (Quick Agenda) I changed the day to April 20.
The display was refreshed ok after a minute.
After that, using again the Quick Agenda menu, I changed the dates again to April 23, but the displaying appointments were not refreshed (they were on April 20).
So, Quick Agenda had the 4 appointments showing on April 23 but the main widget menu was showing them on April 20 (when I clicked on each one to edit, the date was on April 20).
After I opened the settings menu for widget and for Quick Agenda and closed it, the display was corrected to April 23.
Something else I want to ask for, if it is possible to select a span for the days ahead which is going to be displayed in widget (e.g. only the following 3 days, etc.)
Thanks in advance
