1. through chrome plugin: display the tags of video being played on youtube.com. select some some tag and save in a bucket . user will search/watch next video then again our plugin will display the tags and user would select some tag to add to the existing bucket. at any point of time user can modify the bucket and copy/download the items in bucket
2. plug in have to interact with our database and youtube-api
