Have the View Document, Corkboard, and Outline toolbar icons been removed from the beta? I know there were in the stable Windows release (1.97) and Scriv 3 on the Mac. I didn’t know if I have gotten confused because of working with Scrivener 3 on the Mac but I could have sworn they were there. Will they be added back at some point?
ETA: Found them! You can add the icons back by going to View > Customise Toolbar > Main Toolbar. Then you click on the Group mode option to add it. Use the UI srrow keys to position them where you want it.
