It would be great to have an aircraft management page, similar to the control assignments management page. This would allow you to change the tab under which a particular aircraft appears (i.e propellers, turboprops, airliners etc)
It could also allow you to make new categories, Modern military, WWII etc.
Looking at the aircraft selection page at the moment it looks like there is an intention to do this eventually, there is room for more tabs to be added.
What do you think?
