Pro KeePassX integration
Authentication credentials and SSH keyfile passphrases can be supplied by KeePassX rather than being saved in the application's settings.
Pro Local terminal tab
Easy access to the local machine's command-line interface is provided by a dedicated tab shown adjacent to the tabs for all remote connections.
Pro History sidebar
All terminals have a command history of some sort, but this is the only one I've seen with a panel on the side that lists it right before your eyes, and allows you to click on any command you see there and have it instantly filled in on the current prompt line for revision or re-execution.
Pro Per-connection proxy settings
Use different proxies for different simultaneous remote host connections if desired
Pro Scripting support with custom triggers
Most actions that can be performed over SSH can be scripted and set to run on a schedule, automatically upon connection, or in response to a received message or prompt.
Pro Split-display support
Built-in support to split a single tabbed connection display into upper/lower or left/right halves as well as quartered. No need to use tmux, screen or the like.
Pro Tray icon
Application can be minimized or closed to a tray icon to free up taskbar real estate during background operations.
Pro Wake-on-LAN support
Offers the ability to send a properly formatted "wake-up" packet to a device in the event that it is powered off so that a remote connection can be established.
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.
