SUMMARY The way that the system monitor means to get user configuration is very un-intuitive. If I have a custom configuration for which columns to show on a page in the system monitor and I then accidentally enter "edit mode" and click "discard changes" before I am able to do anything harmful in that page, it will reset all the custom columns that I selected to the default, even though they were not changed inside the "edit mode". STEPS TO REPRODUCE 1. Launch system monitor. 2. Go to some section like "processes" in the left panel. 3. Click the three dots menu and select "Configure columns...". 4. Enable extra columns of your choice there. 5. Click the three dots menu again, but this time select "Edit Page". 6. Don't do anything there, but click "Discard Changes". OBSERVED RESULT The custom columns configuration is lost. EXPECTED RESULT The custom column configuration should be preserved, since it was configured inside a different menu.
