This is the best turker tool since HITscraper. I had a few ideas, but I realized once I read the instructions in depth, you had implements almost every idea. The only thing I would suggest is something for a the hit page similar to how Turkmaster would function. So you could add a hit to 'collect' directly from the mturk.com website (outside the GUI). Other idea is for the Cycle slow down to have an auto reset. That's in case you forget to hit reset timer after a minute or so (you could make customizeable like every other feature you've added).
Again, this is incredible. I am surprised there have been only a few to download it, as of yet. This is a game changer, similar to HITscraper.
