When you open the schedule board using the button on the optimization schedule, a new tab is generated, this might give you quite a number of tabs. Hiding them works (e.g. by only assigning them to a dummy user) , however if you now try to open them again from the optimization schedule, you end up with an empty browser tab, the board doesn't load. Suggestions: Even if the SB is assigned to someone else, if you have access to the optimization schedule, you should also be able to open the associated board.

Suggest to assign that specific RSO SB tab to yourself ONLY instead of dummy user, in that case,  other dispatchers won't see that many tabs, and RSO admin still can access schedule-board tab if needed
