ExtJS5 has 3 different scrolling systems?

Diving into ExtJS 5 and talking to some of the engineers behind it I'm forming the conclusion that there are 3 distinct scrolling systems being employed in ExtJS 5. What are they?

  1. For traditional "mouse-only" desktops - using the native browser overflow: scroll
  2. For mobile "touch-only" devices - using Sencha Touch's kinetic "momentum" JS scrolling
  3. For hybrids that have both mouse and touch support (i.e. MS Surface or Google Pixel) - using some sort of a hybrid of #1 and #2 where the JS kinetic scroller kicks in on tap-drag

I'd love to dissect this on an HTML level...

ExtJS5 vs ExtJS4 Config System

With ExtJS5 beta announced last week there were clear efforts on behalf of ExtJS 5 to behave closer to Sencha Touch in regards to utilizing the unique and powerful config system. Last year I wrote ExtJS vs. Touch Config System article to highlight some important differences. Today I'd like to explore this topic in the context of different versions of ExtJS 4 and ExtJS 5 beta.
