The diodon unity lens has made it into the trunk and therefore is now available in the daily ppa. Before it will be released it needs intensive testing. So go for it and grab it.
But before you start here are some instructions. Please remember that this code is in development state and therefore should not be used on a production system:
So let’s start with the installation by running following commands:
sudo add-apt-repository ppa:diodon-team/daily
sudo apt-get update
sudo apt-get install diodon
After diodon is installed you have to logout from unity and login again. Now the Diodon Unity Lens should appear in the Launcher. Either use the mouse or press <Super>-v to show the dash for diodon.
That should be all you need to know. Oh wait, when you want to build from source, note that the Unity Lens is not built by default but needs to be enabled during compilation. Use following commands to do so:
bzr branch lp:diodon
./waf configure --enable-unity-lens
sudo ./waf install
Looking forward to read your comments on what you think of the Diodon Unity Lens.
