Yes this syncup should be added to API Dash

Can you assign it to me?

@animator I reckon I have figured out a way to fix this. Will finish the implementation and submit a PR after testing.

We had a thorough discussion regarding the approach. And we want to focus on user experience and keep it easy to use for the end user who should be able to view/edit the API endpoint without any difficulty. Adding URL parameters in the URL field hampers the readability and makes editing difficult.
Proposed solution:

• Have a separate URL preview section under the URL card (simple text with small font size with copy button) which shows the final url including all the query parameters. Users should be able to turn it off via Settings. Any query params entered in the row will automatically update the URL preview.
• Now, coming to the point - what happens when a user pastes a url with query params or adds a query param in the url field. It should automatically get removed and should get added as a row(s) in the URL parameter section. Note, the URL previewer will show the the full URL including the query params.
