I was looking through the VisualEditor roadmap (https://www.mediawiki.org/wiki/VisualEditor/Roadmap) and did not notice anything about third-party MediaWiki extensions for the editor. Did I miss it?
I do see plans for "non-Mediawiki" extensions (under "Release for third-party non-MediaWiki users"), and also for Mediawiki admins to "easily install and use VisualEditor" (under "Release for third-party MediaWiki users"), but nothing about extending it within MediaWiki. For example, adding a button or menu item to insert a particular parser tag.
Is this by design?
I did notice "Non-template transclusions" on the roadmap, which looks like a way to insert parser tags & parser functions if you already know their name (the way template transclusions work right now). That will be a big help. However, for (say) inserting a given parser tag, it would be great if we could easily add a button or menu item for it.
Thank you very much for any info. DanB
