Sure:
Compact UI (single window UI);
Magic mouse and magic trackpad support.
I’m really waiting/hoping for these since years, I’m not joking, at least since 2011.
Every other mac software, of any kind, has these features nowadays. I don’t understand why sketchup hasn’t.
I love the company and the software, I will continue to be a sketchup user and fan, but I’m really disappointed about this.
