I'm doing a fairly large project in Markdown, and I'm looking for a good editor, either online or Linux-compatible.
The one feature that I'm looking for that I can't seem to find is some sort of structure view, similar to the Structure View in Kile. It doesn't have to be that complicated, though - basically, I'm looking for something that will let me easily navigate between large sections of a text without search or Ctrl+F.
It also needs to have spell check and very preferably a word counter, but it doesn't need to have a preview function. Right now I'm using Draft, which is OK except for the lack of some sort of structure or table of contents view. (I'd also like something with better syntax highlighting and intelligent continuation of syntax, but that's not make-or-break for what I'm working on.)
Any suggestions? If not, I might get fed up enough to write my own.
