AH! First of all, thanks!
More importantly:
Your statement here has led me to realize something.
When you search for Super Text Mesh on google, the top result for docs points toward https://kaiclavier.com/docs/SuperTextMesh.html which are woefully out of date.
It might be worth turning that page into a redirect to the SuperTextMesh.com version or updating them because I have been reading old docs for the past few months without realizing it.
