Writing is thinking. The tool should keep up with the thought and otherwise stay out of the way.
So: a key for every action, no dialog that blocks typing, and plain
text files on your own disk, built into PDF by Pandoc. It is written
in C with a thin AppKit shell. Configuration is config.h.
Extensions are patches. If a feature costs more lines than it saves
keystrokes, it stays out.
It is made for one way of writing. If that is not yours, another editor will suit you better, and that is fine.
Will not do:
There is no issue tracker. If something is broken, send a fix.
Patches go to aray@corollar.io, made with
git format-patch and sent with git send-email.
Feature requests without a patch are not read.
