I hate open/save dialogs. They suck. Specifically, I want the same functionality as...
I don't want to use "Browser View", I don't want to use Quicklook. I don't mind a nasty hack.
How about DefaultFolderX?
More features than I know what to write about, without it sounding like an advert ;-)
I've used it so long I actually find it difficult to work on machines that don't have it installed.
