Feature-wise this is a great update; many new options, the integration of Popcorn and Jam functionality, etc.
BUT... the interface is just an overkill. why fix what aint broken? overall, the new main window is pretty good in terms of visual clarity, but the animated effects are SO superfluous and cheesy, and really have no added value other than gobbling my CPU; luckily they can be disabled from the preferences, but unfortunately that does not affect the barely-noticeable-but-CPU-intensive horrid yellow toast emblem background the "decorates" the process window. WHY?? why should the burning process bring my computer to it's knees because of a stupid background animation??! it seems as if they thought the burning process is too boring as it is, so they should make it "really cool and fun to watch!", and went on and designed this horrendous non-standard black and yellow dialog with big fat text to make it a sight to remember. and indeed you do.

Anyway, as I said, on the feature side - this is a blessed update; but regarding the interface, I hope they'll get their feet back on the ground soon and clean up the mess.
