SUMMARY
The state management behind page Edit mode is surprising in multiple ways that need revisiting. I'm creating a single bug since they seem related from an implementation point-of-view:

* Switching pages doesn't exit edit mode: When editing a page, switching to another page doesn't move the original page out of edit mode. Other page-full KDE applications (like system settings) don't have pages with "hidden state" like this.
* Quitting System Monitor saves all pending modifications **without asking confirmation**. I'm not aware of other applications that require explicit "Save Changes" to apply changes but then silently apply them on exit.

Instead, whenever the user switches pages or exits System Monitor, the user should be prompted with a dialog to ask whether chances should be discarded or applied.
