1) A section view should default to the previously used plane unless a new one is specified. 90% of the time I just want to turn it off temporarily to get the full picture
2) Add shortcuts for the primary planes. Most of the time I use the front or right planes. I shouldn't have to expand the tree and search *every* time I want a section view.
3) Make the button a toggle. I is insane that to turn it off, I have to click the little drop down and go to "End Section View" only to repeat the process to find "Half Section View" If it is off and the user clicks it, he obviously wants it back on. If it is on and the user clicks it, they obviously want it off.
4) Make it more accessable. I use section views a dozen times per hour (I would probably use it more if it was easier). I moved the button to the little quick bar but I still have to use the dropdown.
