Opera Extension Tab Vault lets you ‘store tabs for later without cluttering your tab bar’.
And it’s surprisingly awesome.
Granted, there are loads of ‘save for later’ extensions for other browsers but Tab Vault takes the prize for being the most elegant. Replete with an easy-to-use interface (check out the big ‘add current tab’ button) and some smooth open/close animations the extension, as a whole, feels like it’s not an extension at all but an actual feature within the browser!
Settings aplenty are accessible for tweak-fans however I found the default set to be more than good enough.

The ace Kyle Baker gets a nod for this.
