the addon you suggest removes to much , with that addon the pages loks like we are in the 80's.
we have used only css "Bright Responsive Theme" and some smarty tpl to adapt our store to mobile, and for us it looks better than any theme we have checked in the marketplace.
we are not interested in desktop design, only mobile.
in desktop is everything is easy for every user no mater what theme you use....,
but mobile there is a bit complicated because of the little screen.
our visitors are over 96% from mobile.
we still think that its better to have a mobile optimised store and a webview for app.
we only need to make once changes and it is adapted to andoid and iOS.
