Is there a Library of all Python and C# Custom Components that have been created for RhinoInsideRevit?
No, but I like the idea. There are a lot of 0.x scripts that Ehsan made that are more complex but would require some rework with the changes since then.
I’ve done a few one offs that should be looked at again as well.
Note that the scripting environment will be changing in Rhino 8 to allow scripted element tracking, initially a pseudo tracking then a more robust implementation.
