I'd like to rate this add-on more highly but the first option worries me greatly: '..also >trash< all tabs not active in the last 24 hours'.
Can this be serious? 'Trash' to me, American though it is, means wreck, destroy, obliterate, smash, demolish, vandalise, eliminate, break apart, disassemble with prejudice, make useless for evermore, effectively kill...
Would I want this done to tabs I've had sitting in my browser for more than 24 hours? For any number of hours? That seems absurd.
I'd like to test it, but why would I want a terminal sentence passed on any of my tabs?
Maybe it's just a poor choice of language by the author; very poor, careless.
