It's a documented part of TweakUI, and I find it very usable.  After all, 
it I have my mouse over something on the toolbar, I have deliberately
moved focus there (just as in CDE), and it is very natural to someone
used to this from a good Unix windows manager.  Only a very few 
applications cause me problems (most notably the Visual Basic IDE).

It could be.  Checking them is not, though.

At DSC we seemed to decide that we would need a binary packages mechanism 
for the GUI MacOS X port.  I suspect you underestimate the difficulties 
(or overestimate the abilities of the users concerned): the Windows
experience is that is hard to overestimate the ability of the users to 
make stupid errors and not realize what.

As for this being `just another unix version': if only!  Simple things on
any other unix-alike like making a Rlapack dynamic library became major
headaches on darwin, only, and that is still not fully resolved.
