Does it run as well on old/underpowered hardware as IceWM?
(I really only use IceWM on systems that would struggle with XFCE.)
It's pretty lightweight, so yes, but it does use wlroots after all, so there's a limit
labwc?
I tried it but it was really a struggle to get like OSD or an actual good non-janky taskbar; all implementations are either buggy or cannot be as useful as i was hoping
labwc is closer to Openbox; it doesn't ship a taskbar.
