The Page and building name are shown to the top left of the white area. Below that on the left is the list of all rooms uploaded from the VE model sorted alphabetically.
A room can be selected by clicking on the name in the Room list. The currently selected room is highlighted. You can use the filter box at the bottom of the list to help find rooms by typing the name or part of the name of the room. The number of rooms in the list is shown below the filter box.
The button at the bottom of the page opens the Sync to VE dialog where you can upload a new aps file to update the rooms list.
