Hi @jdaehne,
That’s a bug in the MODX core that has been resolved for 2.4.3, and 2.5. Until those releases are out you could apply the patch manually.
When using the Redactor TV input type, you can control what features are available via its input options; it’s a full Redactor instance without any limitations. There’s been a couple of bugs with that though, so update to 2.0.5 first.
