I'd be in heaven on earth if you could flip a switch and suddenly within the layout editor the layers actually scrolled at the seperate speeds you set AND displayed at the zoom amount you set for each individual layer. As it currently stands its working a bit blind to place tiles and props in all my layers and seeing if it works well in game.
workflow could be : scroll around environment exactly as it appears in game, place objects exactly where you want them
currently its: place with guessing, run game, tweak, run game, tweak, run game, tweak... eventually mostly satisfied and move on to object number two
thanks,
Mike
