I add a new element to the ethereum:elements package, which gives you a simple account select with identicon:
Additionally I improved the {{> dapp_addressInput}}
to it now removes whitespaces and adds the 0x
to any address.
Also take a look at the new improved ethereum:tools, ethereum:accounts and ethereum:blocks package.

(ethereum:tools
works also without meteor, by simply linking the ethtools.js)
If you wonder how to get the static files of your meteor dapp check out meteor-build-client.
