Tooltips could provide more info. For example, #291 includes code snippets and parameter input types.

Should tooltips include code snippets? Should they include input types?

Should inputs include their own type in their own tooltip?

In my opinion, tooltips should exclude code snippets because the code can be messy and confusing to learners, and the code can be viewed elsewhere. I think they should include parameter input types because they act as the function signature, which is a good practice seen in strict languages. I think that inputs should exclude their own type to urge the user to seek the parent block for the entire context, with the type listed there.
