Thanks, good to know you keep an eye on it.
I would like full support for the new Windows 10 ANSI features in TCMD at some point and for that I assume ConPTY is the only way forward.
(I tested the preview of the Windows Terminal myself and it was also much slower -- about 10 times -- than a raw console and TCMD. Possibly because my graphics card is quite old and so forces use of software rendering in Direct2D.)
