Regarding Sidebar credit
The new sidebar experimental feature is credited as "IBM Symphony". Apache guys claim that they have made most of the work:
The core implementation of the sidebar and the framework provided for panel developers is completely new. The sidebar looks similar to the Symphony property panel but shares no code with it.
- Thanks for your suggestion. I think it is true that it is mostly a reimplementation. Hence, I changed to "Apache OpenOffice/IBM Symphony".
