thx @trunalb, good find, will check out the video later (man, it is an hour long). I pretty much understand all LinkedIn techniques. Just lack the time to implement them and support this code for various environments. Ideally this is what JQM team should have provided as a replacement for their barebones and very tricky to use listview widget. Good scrolling/swiping performance is impossible on mobile without managing a sliding window in DOM, like good old editors used to do with files that did not fit into memory.
