Will try that one but so far I could not find better than gdb's tui mode. What's good about it if you're a command line vimmer is that it benefits from readline's vi editing mode if you say so in your .inputrc (although it's not as good as zsh's) So jk go up and down your history and other editing goodies. The only crucial piece of information to use it if you are debugging a program that prints stuff to the screen is the refresh command/Ctrl + L to refresh a garbled screen. It also has source code highlighting if you have the right package installed I believe (gnu source highlighting or something)
