No answer means "no way", right? I really hope you can give me the answer 7 months ago, so I will not keep this unrealistic illusion so long.
After trying the newest Textastic update released today, I get a sad answer. Dropbox API is still outdated.
Maybe you didn't think my feedback hit any bug, but in my opinion no full SSL support is surely a security bug, moreover, Dropbox official change logs show that new API actually has fixed others bugs too.
Hope you can know that I'd not like to request all I want, I'm eager that author can cost his limited energy on what our really want. Of cause I have no right to force you do anything, but I hope you can notice my feedback need a convincing answer at least.
