I was kinda-sorta working on a 2-line mode for LCDproc. I've worked out
already how the screens should be laid out and it's really just a matter =
adding a command line option and then making each screen figure out if =
a 4 line or a 2 line display.
No, it's not elegant, but it gets the job done :)
Realistically what'll happen if you run LCDproc now on a 2 line LCD is =
*probably* one half of the screen will munch the other, and the muncher =
be the one that gets to be on screen. It'd probably still look kinda =
Also I have *no* idea (because I don't remember and I'm not at home right=
:) if the HD44780 supports custom characters. If so, woohoo! If not, ugh.
