Hopefully all addressed in the next release (though some may already be covered in the latest hotfix release).
When enabling the controls for full map, it is basically the same as using the controls for the minimap. However, since there isn't a text display or visible menu tray buttons, I decided to go with a note system that will appear when the controls are enabled on the full map. If there is something preventing the movement, a note should appear to let the player know that movement isn't available for some reason. It should also let you know if a pathway is blocked.
I added an Option under Controls to Auto-Close the Full Map if an event/encounter ever appears while moving. You can also enable the Minimap Toggle Override to quickly access the full map (more convenient for keyboard-only players), or if the minimap is already rolled out, there should now be a button to access the full map in the corner (though clicking on the name of the location will also bring it up as well).
While I couldn't cover everything, I did update the Uveto Space Lift. It works in such a way that is unique from the other elevators, so I was unable to tie it into the same system. Instead, if you are purely using the navigation controls, unless it's the first time using the Space Lift, you should be able to enter the elevator and move up or down (any interrupting events will play as normal), then exit when you are at your destination. It's a couple more clicks than using the button from the menu tray, but at least it is something the map navigation system can recognize and make movement smoother with the navigation controls.
For the Deep Caverns and Korg'ii Hold, it is intentional for those pathways to be blocked in order to make a decision, so the map notes will acknowledge the pathway being blocked. The player will need to close the map for those instances to see the menu tray options.
