Correct me if i'm wrong, but wasn't there an old shareware app for 7.5ish that enabled this behaviour?
I'm sure there was some extension or something that did that. I remember trying (for about 2 seconds) it... It did truly suck.
Anyway, I agree that, if possible, sloppy FFM could be a preference for some (not me) and should be implemented as an optional addition to the X GUI - and I'm one of those frothing mac zealots...
However, this is not something I think Apple should waste a lot of resources on at this time. There's too much to fix that is, I would think without objection, of a much higher priority.
People hated not being able to move/adapt the dock to their liking. Someone hacked out docking prefs or whatever it's called. I use it. I just don't like the dock at the bottom - the right side and hidden seems more mac-like and useable to ME.
You like sloppy FFM. Great. Get to work or find someone else who shares your belief to code it (which, I suspect, is probably one of the reasons you posted this - to find like minded individuals to help figure it out or someone who already did).
So, here's a mac zealot who will cut you some slack.
Aside: I'm actually kinda interested in what was mentioned earlier - issues with Aqua making a window not in front active. I think davidbrit started to get into it. Any actual technical references? Seems like it would probably thrash the sys rather brutishly with X in its current form, but I'm thinking there might be something above and beyond FFM, sloppy or otherwise, that might make use of this...
