[All or Most of The WPMUDEV Plugins] Confirm Leaving A Plugin Page If A Setting Is Changed

Countless times I have forgotten to save settings on some of the Plugin Settings Pages. Only to discover the changes I required are not set.

I believe it would be quite a help if you could keep track of the changes a user makes on a settings page and if the user forgets to hit the save button- Display a Pop up with a warning that the changes will not be saved. Options might be <Leave & Don’t Save> or <Save>
