In complex scenes, it's virtually impossible to select a bunch of related objects.

Doing border select on them will pretty much select the entire scene (how useless is "Select anything and everything in the entire universe that is touched by the rectangle"?). On the other hand, shift-rightclick-select is so inaccurate in solid mode that you will randomly select nonrelated objects as well.

Totally obvious proposal: Make borderselect only select objects that are ENTIRELY inside the border and NOT occluded.

Make view zooming independant of any kind of invisible "center point" which makes zooming simply stop working when you reach it.

Instead, obviously, just move the "view camera" along the view axis.
