+1 to this! The fact that you basically magically transport there from wherever you are, and appear back in the same location after resting, means that it already feels like a pocket plane.
You could also make the object the plane is linked to unable to be used in certain locations if you want to limit long-rests.
Plus fun customisation options like allowing a selectable theme: nature/urban/arcane/divine etc, and the collection of trophies as people mentioned above.
