Re: compositor development=2E I'm building a "DE" on top of Wayfire, which= is an awesome compositor with wobbly windows and desktop cubes, like in th= e good old days=2E Wayfire also has a plug-in system, like Weston's=2E You = could try implementing tiling stuff as plugins=2E You can join our chat on = freenode #wayfire=2E
