Adding YouTube videos to playlists EASY

Recently I have created small tool to add videos to playlists via bookmarklets.
It is called UNEMB and can be found at http://www.unemb.com.
Reason why I have created it, is that it is quite difficult to add YouTube videos to playlists. First, you have to start video, then you have to go to YouTube page, then select playlist where you want to see your video and only after it you can add it. It is quite annoyingly complicated and I wanted to have just one click to do it.
So I have created UNEMB, where you can create bookmarlet that you have to drag and drop to your bookmarks. It can add videos to favorites or playlists, you can have several bookmarklets for different playlists.
After you have created bookmarklet, you can go to any page with embedded YouTube video (Google Reader works great too), and just click bookmarklet. First time you will be redirected to authorization pages (mine and YouTube), but it is only for first time and will be stored in your cookies later. After first time one click will be enough and video will be stored without any further actions.
This service works in perfect synergy with RSSHANDLER, but is good also for other use cases, that's why it is hosted separately.
I am using it myself for little time and already am perfectly happy with it.
My usual use case is that I am reading Google Reader to find something new and funny and once I see YouTube video I click UNEMB bookmarklet to add video to playlist. This is special playlist, it is called 'downloads' and is like my YouTube inbox. I have this inbox configured as podcast in my mobile and in YouTubeXL on TV. And when I have enough time to watch video, I just watch them: later share with friends when it is good or just delete them when it is not.
I found this scenario very usefull and simple for myself and that's why I want to share it with everyone.
Again, service is new and it is first time when I was using Google Data API, so it maybe buggy, so please let me know if you experience any problem.
