It's great to read, that align planar faces feature was included to make life of builders easier. Still, I doubt that this is enough for most of the them, who have got used to temporary & local textures, build math expressions, building hotkeys, rez (and copy) on land group, etc. There are also many non-building related features, including the radar, built-in AO, breast physics, ignore group chat, and so on, that people expect nowadays...
