MDX Editor Sophistication Scale

0: Raw MDX Strings in a text editor

<textarea rows="4" cols="50"/>

1: IAWriter/Well formatted markdown

Still dealing in strings, but with some nice styling and such. Similar to an IAWriter.

2: Notion-like, block-based editor

Visual drag/drop of images, table editing, etc.

3: Full blown Blocks UI

Where components themselves can be pulled in from a library of assets, dragged/dropped and customized in other panels.
