Unload hidden objects to improve board performance

Add a board level setting to unload objects in hidden frames to improve board performance. We often collab with 50+ users who post lots of content. Hiding frames is a natural way to keep the board clean and everyone focused, but hiding frames DOES NOT unload contained objects and improve performance.

It is pointless to hide something when it still in the memory and decrease the performance

Ahh, I though I saw some improvements when I hid my extracted PDFs frames 🤔. I hope it’s the case.
