turn off hibernation of tabs.

Please please please allow turning off the viewing of hibernated tabs in the sidewise window.  I now have the first window with 30 or 40 tabs (4 active) and the rest are  hibernated. I don't seem to remember this before??    Is there a setting I am missing???

The purpose of this program for me is when you have many windows with tabs on each and you want to quickly find the windows visually.  Now there are so many hibernated tabs on each window I can't find the tabs I want and I have to scroll to see the windows because  the first window is so long because of the hibernated tabs.  . Sadly I have unloaded the extension because it does not serve it's main purpose.  

Simple fix.  toggle viewing of hibernated windows and allow viewing of actual windows with actual tabs.
