This is a UI suggestion. I Google searched the forums and didn't turn this up; apologies if it has already been discussed.

I suggest removing the "Livery" button for ships that do not have any available; when clicking this button and 'nothing is available' occurs it's a dead end option and kind of has a half-finished feel.

Better still give us Liveries for all ships or allow us to make them

Custom livery's would be great but just a custom decal would be awesome
