Player controlled map movement

 it would be awesome if Roll20 allowed the DM to set "player pages", pages they can access at will, whilst also being able to "rejoin party", only taking them back to the map with the party ribbon.

Since you have an Elite subscription, you have access to the MapChange MOD (API script) that will allow you to do that, Here is a YouTube video that describes it's use and here is another one  that shows how to help players use it.

+1, while it's good that there's a a script for this, and I'll have to check that out, I can still see value in a feature everyone can use. D&D 2024 added Bastions, a formalized way for players to have a home base, although many tables already had something similar (an inn, keep or temple).  For my players, I like to have a map of their home base (or bases, sometimes the rogues won't hang out publicly with the lawful types between adventures), and having a way someone can switch to "their home" would be a nice feature to have. And if I ever use the shops mechanic roll20 added with the 2024 sheet, having a "market square" with shops would be really cool for those "between adventures" sessions where they're hanging around town, and potentially wandering between home, market, and other places to pick up adventure leads.
