I like the new build mode. It has improved in my opinion.
I am still exploring but one of the things I miss the most is CASt.
I think they should add more color options for walls, floors and decor
stuff. It is very frustrating from time to time and I can't remember feeling
that way in TS3 while building. A simple color wheel perhaps?
That would really make a big difference.
I would also like an option to add and change the pictures that is shown
in the gallery. Sometimes you get really weird angles which in turn makes
the house look weird. That makes me just wanna http://www.freesmileys.org/smileys/smiley-basic/atomic.gif
