How do I configure the launcher to “dodge windows”?
In 11.x, my Unity launcher remained visible all the time, except when the active window went over it.
I cannot find the feature in 12.04 anymore. There is only an autohide (the launcher always hides) and a no-hide (a.k.a. panel mode) option.
How can I get the feature back in 12.04, in Unity 3D and in Unity 2D?

Thanks in advance.
