Ok with 2012 it's official - the developers are falling into the AutoCAD syndrome. They've run out of REAL improvements and settled into the easy route for new releases . . . diddling with the interface.
Autodesk - you've already changed to the ribbon, screwed up the select other, added more confusion to the righ click menu.
STOP IT!
Make REAL improvements to the software, and stop changing where the buttons are. Changing where the delete button is will NOT make me more efficient.
