So, recently @GalaxianGames has displayed ot me how to dissect the code of flowlab.io. 
When I found these, it was pretty obvious that this would be a great feature. I have actually pondered requesting this already, but now I know that it is doable. Can we edit the Loading Screen to be custom, as well as the editor boolean scripts, such as the Mouse Display? @grazer thanks.
Yeah, I really wish to edit the loading screen before the game is done loading. It would add more customization to our games.
@GalaxianGames but could you imagine how awesome it would be to edit the editor? That would be epic lol
