Some features:
- Multiple views into an independent repo of plain text notes (with [some line
drawings](http://akkartik.name/lines.html)).
- Notes can have arbitrary named relationships (links) to each other,
resulting in a graph.
- The primary visual metaphor is an infinite 2D surface of fixed-width,
non-overlapping, notes that can be operated on with an extensible set of
commands.
- Commands usually (but not always) create new columns of notes. Each column
is an independent visualization of a subset of notes.
- App sources can be seamlessly edited from within the app (though packaging
up modifications to share with others currently has some seams; see below)
- Notes can contain hyperlinks in [[wikiwords]] to other notes. Hyperlinks
can't contain spaces. Clicking on a hyperlink opens the target in a new
column.
- A few other things. Explore the command menu and palette along the top.
