> Exclusive use of jQuery, not using browser drag and drop (manually edits element position), using JS to animate and fade/transition instead of CSS, etc. What's wrong with any of these? I get that you may not personally want to work on a project like this, but as a tool you either use or don't, what does it matter whether localStorage is the only "modern" concept being used? Not saying this to be polemic, I would genuinely like to know why as programmers we're always so critical of each others' tools.
