I'd like to single-step through the code displayed in a vim editor window, with all the power of vim to navigate it, plus commands to single-step, watch variables, set breakpoints, etc. tmux or screen can't give me that, nor can gdb -tui.

I was looking for the same thing, ended up using ddd, has watches, breakpoints etc. If you've found a better solution than that though feel free to let me know.

For everything except the data structure graphs, I prefer gdb's -tui option (split-screen code and "(gdb)" prompt) over ddd.
