I think all of this is already on our todo list. We're just very busy and trying to get through things as quickly as possible, but we're just a two-man team!
Pls, put a play/preview buttom that run the layout especyfied on the project option, not that I'm in.
Have you tried right-clicking a layout in the project bar and clicking Run?
) When I put a sprite and set it as "global" its only work globally when executing not at design time.
*All* objects are global at design time. The "global" setting only affects the runtime. You can drag any object in to any layout via the Project Bar. I'm guessing you got confused because the Object Bar by default has a filter on it - see the manual entry on the Object Bar.
