The menu is not structures logically. Proposals:

• Please remove the "Window" menu. It is not about windows, it is about tabs. And the actions there are all better accessible in the context of the tabs themselves.

• There is no real logic behind the location of actions on /with certificates. Some are below "Files" and some below "Certificates". How can this be sorted in a comprehensible way? And without moving most actions to "Certificates", thereby making the menu item list too long?

• We could add a menu item for "Groups", but that would only reduce the actions below "Certificates" by one entry.
