It's missing keyboard shortcuts for some operations (slowdown and speedup) and missing some common shortcuts that other video apps have mostly converged on (unmodified left/right for short hops, up/down for volume). Many of the auxiliary menus are inconsistently partitioned. For example, if you're looking for a color setting in Tools->Effects & Filters, it's unclear whether it'll be under Color or Essentials. These are minor things, but that's what good UX is all about. Tragically, new style guides and frameworks often pitch themselves by explaining solid UX principles then claiming the way to achieve these is a total rewrite using their system.
