# a (probably extremely brittle) script to backup OneTab Chrome browser extension's
# saved tabs (since rarely but at least a few times over the years, OneTab's stored
# tabs have been lost, and it's a significant loss when this happens).
#
# this may all be BACKUP THEATER as I have not tested restoration!!!

# I would PREFER a way to script the
# "'Export URLs' / click mouse in text field / Ctrl+A / save clipboard to a
# text file" UI sequence: LDB files are completely opaque to me (for all I
# know, they're encrypted for security), but this lies far outside my area of
# expertise (and is likely to be browser-specific knowledge of value to me
# nowhere else)

# todo:
# todo: Firefox
# todo: replace OneTab with a more suitable/reliable extension?  (I use OneTab
#       because it's simple and serves most of my needs, not because it's ideal...)
