First step to arrange main menu items in a clearer way:

1. Add subsection functionality that makes it possible to add one or more gray, italic subsection headings to a menu.
2. As a result cascading menu only containing few commands can be shown in a subsection and are thus directly visible to the user.
3. Rename "File" menu to "Start" ("File" is good old Windows standard but on some applications it just does not make much sense)
4. Remove the main menu "Git" and place its three commands under the subsection "Git:" in menu "Start"
5. Remove cascading submenus in menu "Remotes" by adding a subsection "PuTTY:"

Makes this the menus also clearer / easier accessible to you?
