The ‘sentence too long’ can hide a spelling error, which I consider of higher priority. Can this be altered, or could the interface show multiple errors?
I have just done that (here), but not tested it yet.
But when checking the sentence length rule with Dutch on languagetool.org, I see it complains about sentences longer than 12 words. Is that on purpose? It seems rather short.
It is. But as far as I know, I did not set the limit.
The rules I once had were one with a limit of 15, fir easy language, and one with 40. I guess 30 will be an acceptable number. Maybe keep it the same as in German?
