It's nice having 3 different variations all visible at once makes testing a bit easier. The basic design above si the one I settled on it seems pretty simple to understand but needs a lot more love to make it work for all the functioning I have designed. On the good part it already all moves together the system I made with the previous bar works perfectly as a universal system. Much better then the girl cards const line up system. So more of these I guess as I add functionality.
