I use Gmail in Chrome both for my work and my personal email (two separate accounts). I set up the protocol handler so that mailto: links open a Gmail compose window in Chrome, but that window doesn't (AFAICT) allow me to specify from which Gmail account it will send.
Is there a way to indicate this in the "compose" window? Or is there a way to set up the mailto: protocol handler so that all mailto: links send messages from one particular account?
