I love it so much. Because of the built-in tabs!

I'm sure i'm not the only one that struggles with fitting multiple devices on the same screen. Either it's scrunching windows side-by-side, or I take up half computer screen to make sure I can get all of the output (More than 2 screens needed)
Unfortantly its not free! It's so worth the price for being use day after day. And it even works with GNS3... after much headpounding.
Ive tried the collector for teraterm, just didn't do it as well as I had hoped.
