Made some progress updating Handhelj, in terms of GUI anyway:
The buttonbar on the bottom enable/disable, and when they enable, you get a little dialog thing (kinda like the one shown) to setup the particular metadata. The little LJ dude next to the Post button will change to one of the other security icons if you so choose. Will hack more tomorrow.
Also, been reading The Moon is a Harsh Mistress
. Really really like it so far. Can't believe I've gone so far in life without reading any Heinlein!
