Maybe we could ask to have a check box in the Extended Information 
window that show only the selected points/faces. That would provide 
other useful info.

What you can do is a small digital asset with a group number slider. You 
can then plug that out to the node you want and move the integer to see 
only the faces in the current group number. You can have the option to 
show or delete all primitives in that group. It's not really what you're 
looking for but it is sometime useful when you have tons of groups in a 
shatter model for example.
