Hey there Fenloh, good to see another fellow German around
I pretty much agree on all counts, these are some good points. Actually, I'm not fully positive on the sidebar thing either - are you maybe suggesting a sort of Scrivener-like way of handling these, i.e. with categories opening into a "folder view" in the main panel?
On a completely unrelated note, I'm kind of casually trying to kick of a German localization project for the basic data files (either for official implementation or distribution once the content market is released). Any chance I could recruit you into that endeavor?
