Often times it can be hard to remember you need to save the tile you're editing in the editor modal before closing - or else your changes are lost. We should experiment with just auto-saving the change on exit (but perserving cancel to still discard edits). We should toast on exit to make sure users understand we are now auto-saving queries. We can still keep the save button as-is for familiarity.
