I use a mix. If I want to be really precise, I use the dials, but if I use the tools to do gruntwork positioning sometimes. I often use the "top camera" and then position characters with the toolbar, then go in and fine-tune with the dials.

I think it's cool that the program offers such flexibility!

Your layout looks pretty cool, I've often wished the workspace wasn't so cluttered. (And now I'm getting used to 5 with it's floating menus... It seems they always want to float over whatever it is I'm looking at!)

Ockham's right, tho. Accidentally hitting those buttons is obnoxious!
