>>Actually, there is already a certain type of selection filter in MoI. I hope you have noticed the drill-in mode, jonah.

Of course i know that, do you think i'm living under a rock? :) Actually as explained in my reply to Michael it takes some "unlearning" for me to get used to waiting for pre-selection. In rhino you can select edges through objects even when the current shading mode doesn't show them. So i've gotten used to being a little "gung-ho" with my selection methods. I know it's in there, so i instinctly click it...
