Window title is confusing/misleading: it says "House 4 of 5" (Shack 2 of 3, etc) as if it were the 4th house out of 4 .. it took me rather a long time to realise that "House" and "4 of 5" had nothing to do with one another. Maybe the info on the dwellers should be in the window, not in the title bar.

-- no idea if anyone ever saw it, as that forum looks rather abandoned. Most importantly, the UI needs to be scaleable -- the way it's now the game is unuseable for people with high res screens or visual impairments or both.
