Small comment, but why does the text editor show an "overwrite" indictor instead of a cursor indicator when I try to change something in the playground? https://i.imgur.com/OAXbXQ2.png https://i.imgur.com/OAXbXQ2.png I tried typing different things, and despite showing an overwrite indicator it seems to be in a normal insert mode. I have no idea which side of the highlight my characters will be inserted on though.
