i think there should be more than one signer... and some thought needs to be put into how to do it on desktop with browsers

you can recommend people install nos2x or amber, and remove it from your web and desktop versions...

i agree with the principle of it... the more complex an app, the more likely it is to have a bug and if it's a security feature, potentially a vulnerability

people should also be wary not to make these signers into all singing all dancing omni-apps also
