This is exactly what many where requesting, in fact, seeing it in real makes it even more attractive ...
Even better, many things should be added or changed, I've got 2 in mind:
- An option to disable the "hold click to plan route" (this is really bothersome when moving the map around, you plan random routes without asking anything, and even erase an existing one ...)
- Not closing map when planing a trip for fleet carrier and destination isn't available (system/planet full or else)
Anyway, I like what you did here
