My favorites customizability options...
Always use my fonts, ignoring the specified fonts on the website. I recall a discussion earlier that Safari tries to preserve the website as the designer created it, but if you understand HTML, you'll appreciate that websites should be viewed the way the viewer wants it, not the way the designer wants it.
For a while, Safari didn't have a minimum font size feature, which Firefox had for a long time. Further, a size 11 minimum font size is different in size depending on the actual font used. So, if you specified using your own fonts, you'll be sure of consistent behavior.
Cookie preferences. You can disable cookies in general but allow only a few trusted sites (like this forum) to put cookies on your machine. You can do the same with images (ie allow images only from some sites or vice versa) and popup windows also.
Cache customizability. You can even browse your cache to extract certain files or graphics that you might want to copy out. To take this further, when browsing a page, with embedded multimedia stuff (like SWF, MOV, etc), you can hit Apple-I and see all the elements in that page and save whichever you want.
Find as you type, now with text highlighting and all!
Always open every window as a tab. Even popups. Some people may not like it, but I do. But hey, the behavior is customizable! You can even load groups of bookmarks in a series of tabs. Why bookmark one page, when you can bookmark five simultaneously?
RSS already available, while you have to wait for (and pay for) Safari 2.0 to get this functionality.
More advanced things are like using HTTP pipelining, allow SSL pages to be cached, setting animated GIFs to only animate once or none at all (PithHelmet does this also).
Plus a host of extensions and themes! Best of which is Adblock, which is not unlike PithHelmet, though I prefer Adblock to PithHelmet.
And perhaps a few others that I can't think of right now.
Sure, there might be a few quirks (getting less and less), but I can live with that given all the above. Participate in Bugzilla if and when you find any bugs to help improve the software!
