It's possible to create a folders like iOS in unity launch bar?
I mean, you can click on an icon, and then icons will appear horizontal with a few icons.
This could save space on unity launch bar. And I would like to know if these space saving solutions are available.
I've written a little app that is very similar to folders on a Mac dock called Drawers: http://launchpad.net/drawers
You can put just about anything in a drawer by drag and drop. You can even nest drawers inside one another. See below for a screenshot.
To install, run the following in a terminal:
sudo add-apt-repository ppa:ian-berke/ppa-drawers
sudo apt-get update
sudo apt-get install drawers
Then create your first drawer by opening the dash and typing Drawers.
What you are looking for is a "quick list". https://askubuntu.com/a/35526/47291
It is not exactly like OSX or iOS but it will enable you to list folders with one icon on the launcher.
