Ok so here me out. This is a good idea, think about it. There could be many uses for a right click in the game.
Maybe perhaps it could be to right click in your spacecraft loadout and unequip or replace something?
Maybe we could right click a planet (not in the star system you are currently in) and see its statistics without travelling to the star system the planet lies in?
There are many such ideas for a right click in the game. Post your ideas for a right click in this thread because we seriously need to brainstorm this!
Also lemme remind you that discord also had the same idea as well.
