Pin your Chrome tabs

Ok, this is a silly one, but I had to write it due to many people asking me which extension do I use to keep the small tabs on the corner.

It is a default Chrome behaviour, and you should be able to activate it by following this:
1) Right click on the tab that you want to Pin;
2) Select "Pin Tab" [should be the 4th item on the dropdown list];
3) Done =D
