remotehost_applet helps to administrate your remote hosts. You specify the host's address, your login name, and a network protocol, and with additional information about the remote host's operation system a panel icon is created and linked with useful commands. A click on that icon will connect you to the machine, and the context menu offers commands like ping and traceroute. It supports telnet, rsh, ssh, and Virtual Network Computing (VNC).
Complete! suggests words as you type. These words are based on what you have typed previously. The UI will display words as you type; press both SHIFT keys to insert the word.

It is case insensitive for faster typing, and can preload subdirectories containing text files.
