We edit experience page content the full screen all the time for the added real estate… however, to save the changes it takes three clicks instead of just one.
If you want to stay in full screen mode in order to save your work you have to click “update” which closes the full screen view and then “save page”, then you have to click back into full screen just to get back where you were.
Not sure what purpose the update button serves - maybe it could be changed to just save? Otherwise maybe just add a save button to the full screen view that doesnt take you out of that window. Would be a nice little timesaver.
