11.10

There is now an unofficial Compiz Plugin that allows you to move the Unity 3D (not Unity 2D) launcher from the left to the bottom.

Credit to WebUpd8.

In summary:

1. You can now peruse the source-code. Contact the maintainer with suggested fixes! Remember this is unofficial and can & probably will have many bugs still to be ironed out.
2. Install the PPA - ppa:paullo612/unityshell-rotated
3. The packages to install are unityshell-rotated libnux-1.0-0
4. A new plugin Ubuntu Unity Plugin Rotated will be made available in CCSM
5. There is a likelihood of freezes on installation. If this occurs use CTRL+ALT+F1 to start a TTY, login and restart lightdm with sudo service lightdm restart. Rerun ccsm to enable the new plugin
6. This plugin replaces the official Unity Plugin. You will obviously not receive further bugfixes from the Ubuntu development team - you will be reliant on the PPA maintainer to supply bug-fixes

warning please see this Q&A as to potential stability issues using CCSM

Linked Questions:

1. What are PPAs and how do I use them?
2. Source code

Yes but they need to be within their group and files&folders and applications are 1 group. So you can put files&folders above or below applications. There are a few other launchers that are added to this group like the askubuntu (askububtu.place), google books (books.place) etc.

Basically we currently have 2 groups (hold the 'super' key while reading this and look at the launchers): digits and letters. And you can change the order of the group with digits and the group with letters.

Those digits and letters are inside all the *.place files on your system.

For instance /usr/share/unity/places has 3: applications.place books.place files.place

$grep Shortcut *

applications.place:Shortcut=a
books.place:Shortcut=b
files.place:Shortcut=f

(Ofcourse changing the =a to =11 did not add applications to the other group so it will be something inside the Unity system the takes care of this...)
