The experimental point isn't actually true anymore Wildfire, they recently (month ago?) dropped the "Experimental" tickbox since code would improve but no one would ever go and change what heading it was under in the config, thus leading to everyone having to load "Experimental" features ANYWAY. Now experimental features are mixed in with the usual ones except they are supposed to begin with " *EXPERIMENTAL!* " Until such as time the maintainers feel the code is of sufficient quality to drop said warning.
