* test suite (eg, test basic storage and restore of various size data)
* tune hashes on more powerful hardware than thermal throttling laptop
* improve restore progress bar points (update after every hash try)
* If we retrieved enough shares successfully, but decrypt failed, must
  be a wrong password, so prompt for re-entry and retry with those shares.
* servers
* --no-jargon which makes the UI avoid terms like "secret key" and "crack
  password". Do usability testing!
* --key-value=$N which eliminates the question about password value,
  and rejects passwords that would cost less than $N to crack at current
  rates. This should add a combo box to the password entry form in the
  GUI to let the user adjust the $N there.
* --name and --othername to allow specifying those at the command line,
  bypassing the prompts. With these and --key-value, keysafe would only
  prompt for the password.
* .desktop file
* Run --uploadqueued periodically (systemd timer?)
* Keep secret keys in locked memory until they're encrypted.
  (Raaz makes this possible to do.)
  Would be nice, but not super-important, since gpg secret keys
  are passphrase protected anyway..
