Add Stacks To The Unity Launcher With `Drawers`

Drawers is an utility that lets you create stacks (drawers) on the Unity launcher, a feature that was often requested but it hasn't been implemented in Unity, at least for now.
With Drawers, you can create launchers for Unity on which you can add applications, files, folders or links so you can, for instance, have a drawer for web browsers, one for work-related applications and one some important documents. This allows you to have a well organized, uncluttered Unity launcher while having all the applications/files you need just one click away.
