I have not tested it yet, but Zettlr looks interesting:

The developer describes it as: "A supercharged markdown editor that focuses on researchers in the arts and humanities".

(Not an outliner per se, but relevant given ongoing discussions of similar editors.)

Thanks for that. You're right that we talk about many writing tools here, as well as organizing. For me, the "outliner" hook for markdown is folding. Am I correct that this software does not offer that?

Good point. I just installed it, and it seems more simplistic than I expected, although it's still in early development, so worth keeping an eye on.

I'm traveling, so only have phone and Chromebook. How is the speed? Responsive?

I hope the developer's summary of his software isn't true:

"Simply put: Zettlr is the get-together of the best features of existing solutions while enhancing the bad!"

Well, back in August, after reading this exchange, I downloaded Zettlr -- and then promptly forgot about it.

I've just installed it now, and I have to say it's a rather nice poor person's Ulysses: really quite powerful, with a great search function, plus the ability to create projects with subdirectories and "virtual directories' (I'm not quite sure what those are yet -- I've created a couple, but they don't appear to have any settings/parameters, and of course I haven't RTFM yet).

The app is quite large at 170MB, and there's a lack of subtlety at the moment (you can't choose your font or adjust font sizes; the preview screen doesn't appear to work, and other little things are missing), but it's very stable, has some nice features (headings appear at different sizes in the hybrid markdown view; tasks are supported and shown as checkboxes rather than - [ ], and it has a built-in Pomodoro counter), and the search works across files as well as within them (very fast, too, although I haven't got a great deal of data in there yet).

Well worth a look!
Cheers,
Bill

Actually, I lied (inadvertently!): I hadn't noticed that there is a magnification option, you can enlarge/reduce the size of displayed text. Given it's all in Markdown anyway, this seems perfectly adequate to me.

I finally installed this on a fresh Linux system. Not bad! Folding (by header level) is turned on by default and works well. It's missing a few cursor movement commands (move forward or back by paragraph), but it's a pretty slick writing environment, with automatic footnotes, search by directory, live preview. There are a few oddities that I can probably chalk up to my noobie fumbling around, but it has word count (and targets), spell-check, navigation by headings, and more. It also inserts the automatic Zettelkasten notes for files. It has a night mode. It exports to HTML, PDF, Word, plaintext, org, Latex, and others. It even saved a file I hadn't saved when I hit Ctrl-Q (working through the alphabet of commands). And it's multi-platform (Windows, Mac, Linux).
