Putty Connection Manager was a great little wrapper around putty that allowed for tabbed use multiple ssh sessions, as well as sending commands to multiple sessions. Too bad the site went missing. It was a great program, with a few annoyances (especially failure to properly focus when switching between applications).
Enter supperputty. It's an active project hosted on google. Looks a lot like PuttyCM, and can import PuttyCM databases. While it isn't as polished as PuttyCM yet, it doesn't suffer from the same focusing problem (which is something that drove me nuts).
