In all seriousness, it seems to me that interest in Plan 9 will continue to grow from here, especially with 9front taking the lead and actually moving ahead with real development.
Nice. I like the idea of simple and small. I've had a look at Plan 9 some years ago and had the impression it was mostly dead. Nice to hear that there is some movement.
As in a less mouse-driven way to move around? Or just a straight up different window manager?
For the first, 9front has extras on top of Plan 9 – riow(1) and a /dev/kbdtap device described in rio(4) – to allow for more keyboard-driven workflows. It can make rio into a sort of mouse-driven i3/ratpoison-ish thing... kind of.
I autostart it with rio like this:
riow </dev/kbdtap >/dev/kbdtap |[3] mybar
where mybar is a shell function that prints the status bar at the bottom of the screen. That part is used to intercept mouse clicks and turn them into commands for the audio player, zuke.
