So I've paid for all five. Not in that order. Mostly because someone said that A works better with B, then when asked to explain it was told that A and B are the cost of a couple coffees so just find out your self. So I found out, enjoyed it, then was told C was a combination of A and B and this D tweak, with a few extra things. Then later I bought D, because C didn't do D quite as well. Now, E appears to be the best of A, B, and D, and since A was causing problems, I bought E and now I have no idea why because it doesn't seem to do what A does. A = Infinifolders B = Folderenhancer C = Springtomize 2 D = Infinidock E = Scrollingboard What are the pros/cons of these things and why can't I open my friggin' folder in my other folder now!?
