Cons
Con No host list
Has no functions to manage huge numbers of hosts.
Con No way to organize SSH connections
No way to organize SSH connections.
Con Command line tool
It can be difficult to use from a command line interface.
Con No centralized configuration
Each session holds its own configuration of all features. This means that if one wants to change a configuration common to all sessions (say, the terminal font), it has to be changed in each stored session separately.
A better solution would be to have a default configuration and store only the changed elements for each session (both configurations would be merged, with e priority on the specific one).
Con No tabbed sessions
No built-in support for tabbed sessions. Requires an add-on.
Con No mouse support in alternative screens
Like vim, less, etc.
