Tabs 4 and 5 not shown in this particular case.
Yes, I wasn't sure it's a good idea to open the tabs parents when selected from the tree.
What about a right click option similar to "Show in Tree" but "Show in Session"??
I think one of the great uses of the tree is for navigation.
I also think this would be useful to quickly find a widget in complex sessions
It's in sources already 
Just tried it. I love it! I love how it flashes orange.
If just for the cool factor, might I suggest you also make the widget in the tree flash orange too when "Show in tree" is hit in session view?
Makes sense, done.
