What steps will reproduce the problem? 1. Do a bunch of consecutive quick searches 2. Hit the back button a zillion times to get out

What is the expected output? What do you see instead? Either the back button on a quick should return to the previous full activity (that is, Advanced Card Search, Life Counter, Mana Pool, Dice, MoJhoSto), or the Result List / Card View should have a menu button added that lets you return to the main menu.

The first option is probably best, because quick search should be transient (I think), and not persistent.

This looks pretty good. I should note that the label always says "Quit to Search", even when it's bringing you back to the Life Counter. Perhaps it should just say "Previous Activity" or something?

This feature is in the market, so the ticket gets closed. Yay!

I have used it many times with much success!
