Acme has a snarf per window
Snarf should copy the text to the clipboard which it does not appear to do so I cant copy paste outside of DWS (Am I missing something?).
In your Acme, right clicking a file path opens a new window with an error message that it could not find the file. If I highlight the file path and right click, it opens the file. Is this intentional? Acme does not require you to highlight navigable text.
No shell? I see a /bin/9term but no way to run it.
Any plans for a plumber to route messages to the right program or start programs?
Your UI is pretty neat and isn't far off from Plan 9: 9front includes bar(1), zuke(1) audio player, and there is the vdiff directory browser from shithub.us. Window decorations and controls are available in lola, a window manager that replaces rio, also available on shithub. You can also run windows managers in windows managers on Plan 9 without limit.
Though simplicity, 9p and per process name spaces are what make Plan 9 awesome. I run 9front on bare metal on a few machines including my home CPU Server which is also my dhcp and dns server managed by ndb (it can do nat via ip(3) as well.)
The fact that the window decoration buttons aren't square bothers me slightly.
