I use Scrivener about a month. A big drawback is that it does not use OpenType fonts. I can not find the settings, but failed to use any OpenType font in Scrivener. Unfortunately, this makes me return to another text editor.
This is certainly not a deal-breaker for me, since I don't do anything other than very minor formatting in Scrivener, but it would certainly be nice (if it's possible) if all installed Windows fonts were accessible in Scrivener in future.
