Redwood pages customizations (hide or move fields/sections, etc.)

Summary:

I'm trying to see if fields or sections are customizable in Learning Redwood pages via Visual Builder Studio. I have seen a thread in the community wherein I need to check if the customization is possible in VBS.

Aside from the Constants in the Variables tab, which items/tabs should we check inside VBS to see if a field/section is customizable? It would help to get like a list of things (like components, etc.) inside VBS that I need to check to see if modification is possible. Thank you!
