How to improve the building tools

Building should have an easy mode and an advanced mode.
It is too easy for noobies to make horrible mistakes... I wish there was no such thing as a freehand rotation handler for instance. I myself have to click very carefully on the colored circles. It doesnt make sense to me that the freehand rotation area is so large compared to the handles.
In easy mode, it would by default snap to a certain rotation, say multiples of 45 degrees? Most people only need 90 degree angles, you know. That's how you build houses.
Same thing with cut. It would be easier if we could cut prims in halves and quarters. Currently, the only way to make a 3/4 cut cube in an L shape is to fiddle with decimal numbers directly. The easy mode should allow for cut prims to snap to a 45 degree multiple like rotation.
We should be able to set the begin/end position of a cut. It is currently impossible to cut a V or U shape into a single face of a cube, because the building tools force the begin/end position to be in a corner.
Also, rotations should probably be rounded to the nearest integer. At least in the easy/default mode of building.
The easy mode should probably involve some automatic camera aids. When rotating a prim, the UI pops up some graphics that are VERY helpful (thank you lindens!) and let people snap to certain angles automatically. But you have to be turned the right way to see them. This should be automated for noobies, but disableable in advanced mode.
Post your own suggestions!

Things like the rotation snap-to increments could be added to the Grid Options window, then set to 45 or 90 for new accounts. Not only would this make things simpler for them, but it would make things more powerful for the advanced user that wants to make pentagonal walls.

Heh, why dont you code an autorezzor for that? I coded one. It is slightly buggy tho, and I never bothered to fix it. The length calculation for the walls is slightly off, so you would get a spikey pentagon

At least include 'casino', 'club' and 'clasino' with the popular 'mall' as prefabs. It would prevent z-fluttering, low-prim, badly-textured nightmares from popping up on the landscape.
