MoonShell is an Open Source, portable and multi-tabbed terminal.
Those used to working with the command-prompt get used to the many limitations and annoyances, but it doesn't have to be that way with Moonshell. Like all of the author's apps, you can select a theme, and everything is well laid out and easy to understand.
Across the top, you can choose from Places, SSH, Add Tab, Remove Tab, Clear, Options, New Instance, New Admin, Themes, and Help. Help has some useful commands. Beyond that, the app is so simple to use that you won't need further help.
As mentioned, Deadmoon is excellent for anyone who uses the command-prompt frequently; however, even novice users will benefit from its many features.
