I used LanguageTool WikiCheck for articles of Polish Wikipedia. Here is a short list of bugs (in Polish)
Milek, could you check it?
I already did look at that. For example, "da Vinci" should be fixed already.
The error with tzw. „gorących” is a genuine error, not a false alarm at all.
Anyway: please don't guess what's in the dictionary. In most occasions, the words are already there, so these suggestions are even more difficult for me to understand what's the problem. Simply quote the recurring false alarm, and I will fix the rule, as it is the rules that cause false alarms in 99% of cases
