- Performance. The last revision of WriteNow was released 9 years ago, which means that it's still the same 68k assembler it always was, now being run inside Clasic. Yet it feels much snappier than NWX. I know that Cocoa adds overhead, but I feel like a 500MHz G4 should be able to keep up with my typing. It's a quirk of mine.
- Footnotes and endnotes. I'm no David Foster Wallace, but even so, I still have need to add citations from time to time. Integrating with Endnote or any of its competitors would be fantastic.
- Simple styles. At least copyable rulers and fonts a la TextEdit, although a full stylesheet implementation would be best, even if it's not completely configurable.
I think you guys are off to a solid start and I'll be following the beta closely. Good luck!
