I have been wishing for this ever since the company I work for standardized communication on Google Plus/Hangouts (which I don't normally use) with the company Gmail account (which I only use for this, so I'm not usually logged into it). :-/<p>I can use Adium's XMPP support for the plaintext IM stuff, but for Hangouts I have to keep the damn window open all the time, logged into the company account, or people won't be able to call me. Every time someone calls, or I have to call someone, I have to hunt down the window/tab where Plus lives.<p>Wrapping Plus/Hangouts in an app would solve this for me. Anyone know if someone has done that with Firefox or Chrome (on a Mac)?
