Perhaps, one day, I'll add wysiwyg editor for gemtext to MycorrhizaWiki.

There will be buttons on top:

  • Add numbered list item

  • Add unnumbered list item

  • Add quote

  • Add rocketlink

  • Add headings 2

  • Add headings 3

  • Add headings 4 (Note that headings 1, 5 and 6 are omitted)

  • Transclude

And the next row will contain buttons for paragraph formatting.

I think this editor won't work without enabled JS, so text-browsers are left-aside.

I guess it will be implemented using the contenteditable property.

Since 1.1, there's something similar available. Although it is not WYSIWYG per se, it is quite convenient.
