I'd rather Jon ask for more money by ticking the version up and cranking out stuff than let the editor fester like TextMate 2.
That's what I view as honest, "I'm going to work on ST3 to convince you that its worth buying."
I haven't faced the same quality issues you speak of. TM2 has been rock solid for me. The only thing that never felt right was the theme (install Soda) and icon (Yuck, reminds me of Comic Sans)
