There is nothing called Windows 7.1. Windows 7 extended support ends January 14, 2020. Windows 8.1 won't end its extended support until January 10, 2023.
we even have WSL. I think someone in upper management pressured IT to either upgrade or start supporting Ubuntu laptops and that kind of got them going.
is it because it's distributed through the store or because you're on a too old version of Windows? In the first case, you could probably build it yourself and install it on your own
I'd recommend giving it another go and digging into the documentation. They've made the UX much less clunky and support panes now as well as tabs, proper copy/paste etc. My only wish is modal keybindings but if I cared enough I'd send a PR for them.
It was extremely barebones six months ago but it's come a long way, and faster than anything else I've tried.
