Just a small thing:
Can you change how Favorites are displayed in the Tree view?
The icon on the left shifts all the entries to the right and breaks the layout.
Maybe overlay the star icon or align it on the right in the backround.
To be honest I don't like this either but the component we use is very limited. I can't do overlay with it. We want to change it eventually and make sure we can improve the visual. I have written a note for the favorite.
