In the desktop suite we have the sidebar which is a context dependant feature improving user performance eg. in chart editing. Unfortunately it's not the perfect UI for a mobile clients, so the new concept is to tunnel the UI description to the browser and create native widgets there. I did some prototyping work in this area and I can see first results:
As we can see all basic widgets and layout are preserved. All sections are visible, it will be possible to create an UI where user will see only one section at time for better mobile experience. Complex controls like color selectors are not available yet (I'm going to use our color selector present in the toolbar).
