Maybe it's hard to find these days. However it had the best VT220 emulation I have seen running on X Window System.

I will note that I have not seen a terminal emulator that supports the "double wide" and "double high, double wide" character modes of the VT100. Those giant letters were kinda fun. (<esc>#3, <esc>#4, and <esc>#6 if my memory serves me right.)

strangely enough Windows Terminal supports DECDHL but barely any on Linux do!
