• 1. Currently value suggestion is not properly working. It can handle direct types, but not referenced types.
• 2. Node suggestions are not currently suggesting only the function that the parameter type actually is. For parameters that take in a function itself it doesn't suggest everything.
• 3. Validation is really broken. Especially with nested node functions
• 4. Variables aren't suggested in any way. just on the same level, but this is totally wrong.
