sadly, developing the widget is not trivial: first I would like to made it in qt, and this means that it must be revwritten, and then there are some issues like refreshing and connecting to the app that are quite "nebulous" right now. I guess the fastest way will be making a QBW, but for sure is one of my ToDos.
Again on the widget: desktop widget will only update the image or run the app, entering appointment or notes directly on desktop is not possible: otherwise you will not be able to scroll between deskops!

But I have a good news! : the cal sync is working now, thanks to nicolai, and as soon as I get rid of event duplication i will deliver a new release (maybe today or tomorrow).

so let's say: release plan:
1-2 days for full cal sync,
1 week for the widget.
ciao ciao!
