Improve UI+UX floor selector

[anonym-HPI]

As a user I want to easily be able to switch floors.
Make it a list clickable not just small dot, for better UX on mobile (selected is highlighted).
And make the order of floors, the order of the real, like:
3.OG
2.OG
1.OG
EG
1.UG
(and description like this)
