I'm needing a Mac text editor or IDE. I've tried TextMate and skEdit and TextWrangler.
TextMate is great, but I want to be able to identify the matching opening or closing tag of a selected tag - same for opening and closing brackets (code folding is the bastard stepchild of token matching). This functionality is one reason I am a devotee of PHP Designer on Windows - and still not convinced that OS X is in any way a superior development environment.
Until then, I'm using TextMate because it's OK. Basically, my move to the Mac (at work) is being hindered by lacking software offerings.
EDIT: Oh, and I want something that does live syntax checking, so if I miss a closing tag, it highlights the opening tag bright red or something.
