I second that 14th point. I often find myself wondering if the corner of the box i am trying to extract from a list is the correct one, and not being able to figure it out easily, because the points are being drawn underneath the points from the 'bRep components' node. Switching the 'preview' option of a bunch of different nodes to find the one you need is certainly doable, as I'm sure we have all done it, but it can be tedious, especially if you have a really large definition, or if you just need to temporarily turn off the component you ultimately want to display.
additionally, i wouldn't mind a way to change the preview option of multiple selected nodes at once. I imagine it may be possible to get yourself into trouble like this, but I have felt a need for it at times when i realize i don't need to see a whole branch of my definition, and then have to click through all the nodes individually to make it happen.
