The keyboard is fantastic, the best I know for Samsung (the native HTC keyboard is good as well, but Samsung is very bad).

The dictionary download is working (see my question below), I have been using this keyboard for six month now and don't want to miss it (just reinstalled it after resetting my device to factory settings).

One little annoying thing: in the German dictionary the litte but frequent word "für" is missing and for some reason it won't be saved either...
