This might not be the right thread for it (maybe I should create a new thread) but it seems trivial enough that I didn't want to do that.
Anyhow, I have a couple lockboxes set up but what I find missing is the ability to include lockbox balances in the main window where it shows transactions as well as balances. I realize that lockboxes are for low transaction volume or multi-party escrow but for long-term storage, having the ability to show the balances in the main window would be pretty nice.
Well the general idea is that the main window is for showing you funds that your wallets have exclusive access to. If someone imports a 2-of-3 lockbox (or someone plants it there), where you're only one signer, then they can send it money and make you think you received it (if you're not a savvy user). Then they sweep the money out of it later. We've seen users do some pretty "dumb" things, and by "dumb" I mean "they don't understand Armory, Bitcoin, transactions, multisig and/or all of the above."
For that reason, we wanted to keep it separate. And as you said, it's mainly for low-volume of transactions and where you may not have full signing authority over them. However, I had thought about adding them to the main screen with a green tint (like offline wallets have a blue tint). That would help identify that it's different from your regular wallets (though the interface might be a little too colorful). Most likely, I'll just wait for the new wallets to be done, and then have M-of-N wallet alongside the regular wallets with a green tint. Lockboxes can remain separate for escrow situations.
