Nice! Small comment about the markdown view, it shouldn't say "Preview", I think that makes sense when you're actively editing something that you have the option to preview what you are working with, in this case it would be something like "Rendered" or similar.

Instead of "Object", could we display the schema label?

LGTM! Small nitpicking:

• changelog could be better formatted
• When clicking on re-generate, we could invalidate the query options of tasks count to retrigger a fetch an show the pulse
