Kartik K. Agaram a5cb7381a8 experimental app: zettelkasten
https://merveilles.town/@akkartik/107742821323590471

What we have so far:
  a representation (see 'zettels')
    parent/child
    next/prev sibling
    (todo: misc cross-links)
  ability to render zettels in multiple columns based on 'view_settings'
    all zettels render with same size
    alternate backgrounds between zettels for legibility
    skip rendering duplicates (if we ever hit cycles)
  a highlighted 'current zettel'
  ability to move current zettel
    by screen location (arrow keys)
    by network structure (h/j/k/l)

Still can't edit zettels or load/save from/to disk.

# .tlv file generated by https://github.com/akkartik/teliva
# You may edit it if you are careful; however, you may see cryptic errors if you
# violate Teliva's assumptions.
#
# .tlv files are representations of Teliva programs. Teliva programs consist of
# sequences of definitions. Each definition is a table of key/value pairs. Keys
# and values are both strings.
#
# Lines in .tlv files always follow exactly one of the following forms:
# - comment lines at the top of the file starting with '#' at column 0
# - beginnings of definitions starting with '- ' at column 0, followed by a
# key/value pair
# - key/value pairs consisting of ' ' at column 0, containing either a
# spaceless value on the same line, or a multi-line value
# - multiline values indented by more than 2 spaces, starting with a '>'
#
# If these constraints are violated, Teliva may unceremoniously crash. Please
# report bugs at http://akkartik.name/contact
