What I like is whole terminal stuff. What I don't like is that not all commands work as should. For example you can't pass arguments to functions, ls -a doesn't work.

This one is too programmy to feel like I can do much of anything... Here's a tid bit that may be helpful though: on the CSS for the terminal there is a call for a font "VT232" or courier. Working in graphics and searching the appropriate repositories turns up no such font ever. Perhaps "VT232" is a useful code at some point.
