This looks neat. What Steem node is this connecting to to broadcast transactions? 

Offline signing tools have been a niche feature that certain users have wanted or needed but has so far been unfilled. Can this be adapted to do offline signing as well?

Currently wss://steemit.com/wspa but it could easily be made configurable.

I'm not sure that I understand your question about offline signing.  Since it basically signs off-line before transmitting only the transaction that was signed -- yes, it could easily be adapted to sign anything . . . .

Like you can sign Bitcoin transactions using a computer that isn't connected to the net, then take that transaction and broadcast it from a node that is online. Kind of a secure, air-gapped solution. The demand isn't super high, but it's one of those features that is good to have to have airtight paranoid security.

Maybe I'm ignorant and that kind of thing isn't possible with Steem, as I'm not familiar with the technical details of transactions, and they might need up-to-date block information.

That is precisely what this does.  It signs the transaction in the browser and then transmits the signed transaction to the node.  It would be trivial to change it to write out the signed transaction for transfer to another machine while it's own machine is disconnected.

Actually, it's easy/interesting enough that I'll add it to the next release.  Thanks!
