I tried using the LanguageTool add-on in LibreOffice, but it doesn’t seem to respect the dictionaries I already have in LibreOffice. If I have a word added to a LibreOffice dictionary that LanguageTool does not know, LanguageTool will mark it as a spelling error. There also doesn’t seem to be a way to add words to LanguageTool from the LibreOffice interface. Am I missing something, or is this how it is supposed to work?
