Hello I translated sidebar in LibreOffice which (how we know) comes from AOO4. I see your project suffer from lack of Polish translators so I thought it would be fair, giving back something from LO community.
I downloaded ZIP file from Pootle and looked for "sidebar.po" files. All files are included in attachment. Today we anticipate LO 4.1 beta2 release and I am about to farther polish our translation. If you are going to use them I can send you these files after every update. http://www.fastshare.org/download/Polish_sidebar_.zip
