I was browsing BGG’s game page and saw this thread. Since it’s user developed graphics, there wouldn’t be game copyright issues and the guy uploaded the graphics freely. Any chance you would chance to use this graphics here? After asking for his permission, of course....

I think it would be nice if you could add the actual graphics of the booster and research tokens when you hover on them. I ended up pulling them out of my game to visualize it better and still accidentally picked the wrong one once.
