Pro Window tiling
Very elegant keyboard shortcuts for creating and navigating between tiled terminals within each tab with no appreciable lag.
Pro Extensible Kitten framework
Supports plugins to add features one at a time for those who need them. Examples include Unicode input and side-by-side diffs.
Pro Tabs for multiple instances
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
Con The developer officially abandoned the project
Early in 2017 the developer announced that he had no interest in continuing to develop it. Not a single line of code has been added or improved since then,
Con Heavily dependent on long-forgotten libraries
PAC Manager draws its underlying terminal functions from the Perl libraries written to interface with GNOME Terminal, circa...2006. The libraries have been untouched for at least five or six years, and just recently have begun to be removed from major distribution repositories like Debian and Ubuntu. It's a chore to get them installed and will only continue to get harder.
