If you had problems with getting console input or console manipulation (you miss things like conio.h), Powerutils is for you. Powerutils already contains a dynamic fgetline function, a pause(), a gotoxy() and also a clear().
nScreen is a terminal manager like GNU screen. The difference is that it will connect to several machines (using an SSH tunnel), so you're able to control them all simultaneously.
