Mobile Phone Compatability
I guess that this is really a statement. Muse is way behind the times with its work around to make it Mobile Phone Compatible. The idea of rebuilding an existing site in phone mode sucks. Setting responsive mode is still a work around and doesn't suit all situations. The amount of money I have invested and still invest really annoys me, when the likes of WP and google.site just to mention a few, automatically convert your site to Mobile Phone Compatible. Get with it Adobe.
