I don't muck about with having to use tabs or maybe keycodes to change the current view(s) of a terminal/xterm.

I simply open sufficient xterms on one or more virtual desktops to cover all of my needs.

Ferinstance: I can have the warnings and errors of the last compile displaying in one xterm, I can be editing the relevant xxx.c source file in a second xterm, the associated yyy.h header file being edited in a third xterm, and the man page for a library function showing in yet another fourth xterm.

All of them immediately visible, and all of them interactive.

Unix as IDE 'just works' for me.
