Is it possible to add own question type by a plugin? Or what are the plans for this? I found www.limesurvey.org/manual/Question_object_types but it is almost one year old.

Not really,
Currently solution are

- QuestionTheme : update HTML view (and JS) of existing question type
- With plugin : but you can not create a complete DATABASE system : you need to use existing question type … gitlab.com/SondagesPro/QuestionSettingsT...ionSpreadsheetSurvey use a long text questoion type for example.

Thanks. So a plugin could kind of change the type File upload to be a Record your answer -type or Draw your picture -type.

Maybe you can trick UploaderController function and use a QuestionTheme here ?
See : github.com/LimeSurvey/LimeSurvey/blob/c8...rController.php#L121

But yes : a plugin can do the trick too
