Operate several terminals from one window using the tabs feature, allowing you to make simultaneous connections to different remote hosts.
Pro Scrollback buffer viewer
Allows for viewing the scrollback buffer in an external pager of your choice ('less' by default, with support for 'more' and 'most'), a huge benefit for turning actions taken in a live terminal session into a script for efficiency or dissemination or collaborating on workflows.
Pro Controlled and configured from the shell prompt within the program itself
No graphical menus to clutter the screen saves system resources and time once you learn that all those options are still available from the command line within the app.
Cons
