Could you elaborate on what some of the bugs you ran into were? I came across it the other day and was eager to try it, but reticent to spend the $10 without a demo (currently in between jobs)
Oh, stuff like windows becoming unmanaged, Tyler becoming disabled until a restart, windows moving around without you wanting them to. It's pretty much an alpha product - don't spend yet, wait a couple months and see how it goes.
Last I tried (admittedly a few months back) it was still alpha-quality. I.e. the entire screen would get shuffled unpredictably, windows would end up misaligned (partly overlapping each other) etc. - nowhere near usable.
