The menu is not structured logically. Proposals:
* Move "Perform Self-Test" to the Tools menu. Position there at the top? Or position 2?
* At the top is currently "Show GnuPG Configuration" which should be renamed. Suggestion: "Open GnuPG command line". (As most other entries there start with a verb.) The first thing choosing that entry will currently automatically do is "Show GnuPG Configuration", but we might change that when we add additional commands and have it wait on a user choice before doing anything.
* 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.
