Hi Carel,

This is very kool plugin that I would love to use. I compiled your plugin
sources and looked at it, it looks great. I don't see any place in your
code where you are using setExtraAdditionalFormats, I tried adding below
code which highlighting the line in below function and it does works


TextEditor::BaseTextEditorWidget* editorWidget =
    if (words.count() != 0) {
