This editor does not support the wizards for filling out the cite book, cite news, etc., templates that I rely on heavily. So it's unusable to me, sadly.
Topic on 2017 wikitext editor/Feedback
Sandstein, which wizards are you using? Is the (built-in) citoid service (toolbar > Cite > Automatic) not working for you?
Thanks - I didn't find that function. But it doesn't work how I want it to either. It only allows fully automatic or fully manual filling out of citations. It does not support filling out what it can automatically, and letting me fill out the remaining fields, which is how I've worked so far.
You can do that. Start with the automatic form, click "Insert" to add it to the page.
In the visual mode, you can then click "Edit" to fill in the remaining fields (or to fix the ones that were wrong) in a dialog box. In the 2017 wikitext mode, you can manually edit the wikitext.
