Not sure when this will be added, but they need to do some serious work to the app. It SUCKS right now.
I'm very disappointed in YouTube/Google, with the lag and buffeting issues (on phone and computer), and the poor quality of videos over 3G makes it just an unpleasant experience overall.
I shouldn't have to pause a 5 minute video for 10 minutes just to watch it when I'm running Verizon FIOS via Ethernet.
