The following filters (the first two are my favorites!) do not work in Moodle desktop and Moodle app"
- collapsible
- embed question
- TAB in Text
- jMol
- SageCell (also failing embed link to online SageCell: https://sagecell.sagemath.org)
Other filters who work:
- VideoEasy
- Generico (with exception of layout issues like in the post-it example or countdown_A04)
- Combination of TeX and Bret Victor's Tangle javascript works (see picture)
- Also HTML Simulations created with Netlogo Web work nice in the desktop
By the way, TOC of a book module becomes a strange "Dog ear"
