@DiegoMagdaleno probably not as much as you think. The syntax for it looks quite similar to a yaml config format I’ve been wanting to make part of either Kinto or xkeysnail actually. That would have been a simple translation layer though.

Just wanted to highlight some cool work that rvaiya is doing in keyd here: https://github.com/rvaiya/keyd/blob/master/scripts/keyd-application-mapper

In this latest beta, keyd now offers its hot-swappable keyboard layouts and layers with application focus conveyed by that python script via a socket to the keyd daemon. Works on X, Wayland+Sway, and Wayland+Gnome.

That is very interesting, I've not used sway any.. and sadly my distro of choice, Ubuntu Budgie, does not have access to gnome-extensions even though it works with gnome-shell still.
