Hi All,
It would be useful if it was much clearer which side of a wall is inside/outside/left/right. Whenever replacing a wall with a new wall style for instance, I've been adopting the trial an error approach. I know the wall when selected shows a tiny arrow on one end, but often this is obscured or out of view. Also (more importantly), this is not displayed if you have more than one piece of wall selected.
So the typical workflow of selecting a bunch of walls to update/replace, guess a side to align, get it wrong, undo, redo, select opposite side align.
Whilst I'm on it, a marker showing 'inside' and 'outside' of window objects when selected would also be handy.
