Rated 4 out of 5 stars
I wanted something similar for a long time and even wrote an add-on that barely tackles it - but this is even better than my original concept :D I will rename my add-on to deprecated and tell my almost 50 users to switch to this instead!
I will change the rating to 5 stars when there is a shortcut to activate the add-on (for example: ctrl+alt+h) and when the add-on exits hack-mode after isolating an element. Both could be options, and I'd be glad to help in any way!
EDIT: Thanks for the reply Silver! There doesn't seem to be a new version out yet so I can't test the changes. Could you please consider also exiting hack-mode after isolating an element?
No Need for a new version already built in. Access key:Context Menu access key = "H" (was "A")Tools Menu access key = "B"Usage:Contextkey, h (or Shift+F10, h)Alt+t, b
