Wanted to better summarize this, as legacy ie and non-chrome based edge are now out. This is a pretty big milestone.
I was a pretty big fan of jQuery and jQueryUI at one point, I find the look/feel very dated at this point and somewhat clunky. It reminds me of Windows XP's Fisher Price look in the worst way.
All said, I am glad to see the significant reductions in size/scope and ongoing support for modern browsers.
