>We recently had to wrangle a bunch of 400Mb+ XML files, and everyone else’s editor struggled even to open them, while I happily regexed my way around extracting various data

Way back with version 4 (I think), I used it to work on a CSV that was way larger than the amount of RAM I had in the computer. Amazingly responsive. Not that long ago I used it on some XML monstrosities that were pushing a gig in size. Still worked.

I still use it as my main environment today. Over the years you accumulate a variety of little snippets and scripts (in all sorts of languages, including AppleScript) and whatnot that help with your particular workflow. It's very much like a prettier, pointy-clickier version of Emacs in this way.

I really miss BareBones Mailsmith, which was like BBEdit for mail. In today's world where everybody uses HTML email (boo!), it wouldn't be so great, but man alive it was good.
