In terms of no results, thats something I'm still working on, for some reason sometimes the query to google/youtube doesn't return anything. If you try searching for something like "trailer" (I know that query works) you'll notice they are the exact same results of youtube.com though you can only view the first 50.
In terms of what you would use it for...personally I use youtube a lot to listen to music and back when I started working on this there was no way to continuing listening/watching a video while at the same time continuing to browse for other videos to add to a playlist. I know youtube has something similar with its queue thing but it still isn't exactly the same, at least I don't think you can watch a video while you still browse to add to your queue.
Date of upload is something I can easily add, same as date uploaded so if I get the chance I'll stick those in.
