Add confirmation dialog if the editor is closed with unsaved changes

[nzminecraftDOTcom]

Some web pages (Gmail etc) prompt you with a pop-up asking if you wish to close the tab and throw away any changes you have made

This would be useful on the editor, because rewriting 50 permissions when you haven't recently saved it is annoying. - Personal experience.

This should be possible to do, if the editor has modified data and hasn't been saved I can throw a warning before you close the window.

Not sure if this will be more annoying to some people, though. I know I get really annoyed whenever a website does this to me lol.

I'm sure it'll be a pain to some, but it won't need to pop up if they're just opening the page to look at the permissions, without making any changes. If they make changes and don't save they'll probably be relieved that it warned them in most cases.

That should be implemented.
