This extension is quite helpful with the ability to create different short cuts and label for each AWS accounts. I use this daily managing multiple AWS accounts and environments.

The developer is very responsive and open to suggestions.

I discovered this extension when looking for a solution that would reliably allow me to define a list of shortcuts to favourite AWS services in the top bar of the AWS Console.

This extension does just that and MUCH more.
Ability to select favourite regions, and links to "Datasheets" (which are super-awesome and gather in one place everything you might need to know about a particular service) is equally useful.

Now that AWS decided to remove the "shortcut bar" completely, I'd say that it's even more useful. I simply love this extension!
