When I start certain applications (eg mplayer) I’d like those windows to be “Always on visible workspace” (ie. sticky) automatically. I used to use devilspie2 in the X11 days to set this attribute but this doesn’t work with Wayland on Fedora.
Is this possible with Gnome/ Wayland? Is there an extension? Something like devilspie?
Each process in Wayland only has access to the windows it creates, and nothing else; the only (privileged) process that can access all the windows is the compositor, so you can’t have a “Devil’s Pie” application, but theoretically you could write a GNOME Shell extension that did window matching and applied some rules.
