--- Comment #3 from Kevin Kofler kevin@tigcc.ticalc.org --- FYI, Unity 2D is dead, discontinued by upstream (Canonical). It relies on QML, and QML will require OpenGL in Qt 5, which defeats the purpose of Unity 2D. So now I think the fallback plan is the normal (3D) Unity on llvmpipe. In any case, they dropped support for Unity 2D already.
I also don't see how it would be any more convenient for non-Unity users than plasma-widget-menubar is for non-Plasma users. You have to switch to Unity to use it, just like you have to switch to Plasma to use any plasma-widget-*.
