When creating more complex GUI layouts and 2D games, it’s very limiting to find that there aren’t a lot of ZIndices on GuiObjects. Bumping this up would be good, but an unlimited number would be great. Even though this could cause an issue with overlaying the Roblox interface, there must be a way to make sure that the menu button is always on top.
I think this has been a limiting factor for GUI development for a long time, and really needs to be addressed.
