I´m using Lightroom CC in german. (Mac OS X, 10.10.3).
In the english version it is possible to adjust the width of the sidepanels considerably.
This adjustment can´t be made by the same amount in the german version!
Is there any hint about that problem?
Thank you for your answer.
This IS my problem. The english version allows to drag the side panel considerably more than the german version...
It's undocumented, but if you hold down Alt (Windows) / Opt (Mac) while you drag, you can make the side panels any size.
