Let us use our Google signins in Google Maps and in You Tube so our saved locations in Google Maps and Favorites in You Tube show up on our phones too (and so we don't have to duplicate everything in the saved locations and videos there).
Please, just completely rebuild the YouTube app from the ground up so it's easier to search for things. Why can't I search by date added? Or see an uploaders other videos? Or have subscriptions? Or anything that might make the device even slightly useful?
