Components
DTube is a decentralized streaming video platform linked to Steemit (the decentralized social media) which allows users to upload videos easily and make money (or cryptocurrency) through the upvotes on their post.
Proposal
Dtube is a fast growing video site and I noticed that it lacks the add to playlist shortcut. So I want to propose the implementation of add to playlist shortcut on videos. I recently suggested the addition of playlist feature to the main interface of the dtube site. Upon the implementation of my former suggestion, the addition of the shortcut will be necessary.
Mockups / Examples
This is the interface of YouTube with same feature
If implemented, the add to playlist feature will look this way on the dtube interface. 
Benefits
It will be easier for users to add their favorite videos instantly to the playlist feature which is yet to be implemented.
