Same here. Need its tabs since it is difficult to organize many terminal windows if use rxvt. I also use LXTerminal on the same machine. It's set to dark background to make flask's debug message easier to read. LXTerminal is very lite and adds very little(or no) additional dependence on Debian.

Me too, but mostly out of laziness and because its good enough once you change the color scheme, disable the menu bar and reduce font size slightly. Also set a very large scrollback buffer.
