Perhaps I have been doing this all wrong but I find that updating and maintaining menus to be particularly difficult.
I can't see any further than the camera in the Project Window so I have to copy a menu to the Hierarchy window, edit it from there, after editing I need to delete the asset in my Project window, drag it back in from the Hierarchy window and then delete my old asset from the Hierarchy window.
Is there a better method than this? I have to do all this to simple change one thing in a menu, many a time I have deleted the asset I have just created by mistake or mistakenly edited a menu whilst the program is still running and then lost all my progress when I clicked stop.
