Most of these things work fine (though with wayland-specific tools, rather than X-specific tools), except:

> (4) global indicator of where my cursor is (xeyes)

AFAIK, no tool allows you to do this. The issue is: clients generally can't snoop on input when they're not in foreground (e.g.: to make key-loggers less trivial).

A privileged client could do this using something like layer-shell. It's a hack, but it should work. Somebody needs to write it tho.

> (5) define global key combinations that launch programs (xbindkeys)

Compositors implement this themselves for the above reason.

I guess this should work with XWayland? Keep in mind, most X applications work via XWayland. This means normal applications; xbindkeys or xeyes won't work since they rely on reading input when other applications are in foreground.
