Just a little suggestion for the android app: You can currently open the in-game tabs like the inventory by touching the respective icons, but you can only close them by clicking outside the tab boxes, forcing a move/use click on the map. It's not super annoying, but it'd look cleaner if you could just close the tabs using the icons as well.

It would be nice if you could close the tab by touching the icon of the tab that's currently open, so in case of the inventory, touch the bag to close it. Then you can just open the inventory by touching the bag, and then touching it again closes the inventory. Currently, nothing happens when you touch it again.
