Alert when not the owner (write access) of a display when entering "build mode"
Often work has been done on a PI Vision display (with a known/published URL) only to realise you were not the owner when hitting the "save" button. A prompt when editing starts, or keeping the save button in the "inactive" state if not the display owner would help prevent this re-work.
This would save lots of re-work and frustration! Even just seeing the current owner displayed when trying to edit would help.
(Being able to change all the settings such as owner, sharing etc as an admin from the editing window would also save time rather than navigating back to PI Vision home screen and changing from there.)
