Small simple teak to UI

i noticed that we dont have floor indcators on UI
so i wasnt sure which floor i was on so only way i know which floor was looking outside or placing numbers on walls but surely a floor indator on UI

examples:

Airport ceo has Floor indcator on left side on bottom bar

Stationflow has floor indcatior on right side at bottom showing levels

Sim airport has indictor on right side on middle
