A few little notes. (These regard build 8A425.) Generally very good. Very responsive. I don't know if it's as fast as Panther, though...odd. Maybe it is, and my machine's just freakin' out. Maybe I need to clean out my user library, or something.
I do have some issues withe the Get Info panel in the Finder, specifically with the permissions sections. I was trying to mess with some permissions (more on why later), and once I chose a new user/group (my own), I could NOT change the read/write/read+write pop down menus. Also, once I clicked the lock, they switched back to the old user/group pair (system/admin), although I checked via the Terminal and they had been changed. Odd.
I was messing around with all this on my /sw directory (Fink) so that I could get it in the Privacy section of Spotlight, 'cause I don't want to see all those files in Spotlight ;-). This is a little more difficult than I thought, and I'm not sure about it, yet. First off, the privacy is global, for all users, and anyone can add a folder to the global preference given that they have _write_ access to the folder. (At least, that's been my experience.) Given this, I think there should have been two types of "privacy preferences." One that is something like "I don't want other users to see these files" and another that is "I myself don't care to search through these files everytime I use spotlight." That way I could add my personal files to the first, and add /sw to the second. That seems to make more sense to me.
That's it, so far.
