I currently have the white apple theme (customized to my tastes), and i want to attempt to try a new theme. So I backed up the theme using springback. Now i converted to the "vending machien" theme. and there are categories folders and etc. If i were to delete these folders, or disable categories, will springback reopen them. ALSO, if you are using springback, they warn you not uninstall apps that were in the backup. Is it okay to have new apps as you install the back up?
