What annoys me about Scalos is that, in the wake of OS3.5 and 3.9, it still (AFAIK) insists on being a total replacement...and on using MUI. I played with it a year or two prior to OS3.5 when it was a little unstable, and it did some nice things, but today I don't WANT to replace things like window scrolling and icon dragging, which work reasonably well right now. I'd be pleased if they could find a way to transparently patch only the things the OS updates missed, like the window text modes (ie. View By -> Name, Date, Size, Type). On the other hand, I haven't tried it in a while...
