Wakelet - Enable Wakelet extension for new tabs - create a collection or drag individual tab to a collection
Wakelet is an amazing tool that allows you to create a collection of anything you like that has a link. Wakelet's extension allows you to create a collection of open tabs as well as one I overlooked in the past. The overlooked feature is the ability to drag individual tabs to a collection in Wakelet.
Embedded below is a 37 second YouTube tutorial as well as a collection about Wakelet.
