* fix FIXMEs
* fix logging output
* fix logging output (that is, make it log anything)
* put git short id into version string
* make sure cookie expiration is correct
* sessions maybe
* configuration in db to support password changes
* perhaps load the target in a fullsize iframe so that the target can be
changed by the js on server update instead of having to reboot the display
box

# status
This is not enterprise-production-grade software yet.
It has a CSRF bug (low severity) and it stores your unhashed auth password
in a cookie. I didn't even check how long the per-device cookie expirations
are, so it might have a big painful bug there too. I made it to scratch an
itch and I am running it in production; I may improve it further but it
works for my purposes (being able to flash a half-dozen display driver
raspberry pis with the same image) as-is.
Patches and improvements and bug reports are welcome. Send me an email at
the address below.
