The free version allows you to make two different HUDs, one for the map and one for battle. The PRO version allows an infinite amount of HUDs that can be called with conditions you can event. You might be able to make 1 customizable menu with the Map HUD of the free version if that's all you needed and I am sure it would work fine. I imagine it would simply be the map HUD and using conditions to turn it off and on and not as the same as if you had the PRO version, but to make multiple menus you definitely need the PRO version. I think the free version is still excellent, just if you are planning a complex menu system I don't think the free version will cut it...
