Xonsh. For basic use (running CLI programs with arguments) it works like any other shell, and for other uses it has nice Python syntax (and libraries!). For example, I like not needing a separate calculator program, as I can do maths directly in the shell with an intuitive syntax.

I like Terminator for its mouse-controlled multiplexing. I also like the fact that it’s made with Python, although I haven’t utilized this fact in practice.

I’ll start with Shiofaioth:

Fuin huomo, aokae lie-laik-duei mas uin toroic kuin uin poulaiseir, bue-ecoidae-duei faelid dai opia, daet hui toroic soe-baisen-xoai iroitedaefa hein touras huic poulaiseir-ki duil Rio Hudson.

I don’t know what Nitter is, but I think bird.makeup might be what you are looking for.

Check out xonsh.

I’ve got used to XFCE.
