What's your favorite text-editor?

iA Writer, designed for Markdown, available for Mac, iOS, Windows, and Android

Notational Velocity has an unusual interface, designed to make adding to and retrieving from a large repository of notes. Since it supports storing your notes in plain text within a folder, it just works with Blot. It's available for Mac.

Obsidian, stores a 'knowledge base' in a folder of text files. Blot supports wikilinks and backlinks too, which makes it a good companion to Obsidian. Available for Mac, Linux and Windows.

byword has been pretty nice to use. not many bells and whistles, but gets the job done

I am wobbling between VSCode, which has a pretty good Markdown mode and Obsidian. My main complaint with all of them is, that none support either iPadOS at all or, in the case of Obsidian, don't support Dropbox. For a while, I did take the more involved roundtrip via Git (using WorkingCopy on the iPad) and I did experiment with using rsync, but neither is 100% transparent on iPadOS.

If anyone has any idea how to use Obsidian on iOS and sync the iCloud folder it uses on there with a Dropbox mount... I'd owe you at the very least a big pizza...

I usually write in Ulysses, which syncs perfectly to Dropbox, which makes it very easy to use on all platforms. Ulysses does have weird interactions with link names (photos inserted into posts) that start with an underscore, such as "_photo.jpeg" when saved in Dropbox, as it sometimes escapes them when opening (creating "_photo.jpeg", for example, which then is broken in Blot. For the most part though it's a good experience.
