Feature request: session persistent study chapter arrows/circles for non contributors

[Siderite]

Let's say I am watching a tournament, or a broadcast or examining a study with multiple chapters. As a non-contributor, if I draw shapes on the board then switch chapters and come back, the shapes are lost.

I am considering this specific scenario: I am watching a broadcast, I mark the moves that I think the players should do, then go to another board. I would like to go back to the first board when a move is made and compare to my prediction.

I think this would be a good idea and not a very intrusive one, if the shapes are persisted in the session storage only.
