Viewing and editing query parameters is not a pleasant experience.
I'd prefer not having to switch to Postman for editing and sending requests, but its UI is currently so much better for this task.

FWIW, one non-obvious way to get a richer editing experience here is to SHIFT+Click on the Execute button. The new request will be created and paused at a Request breakpoint. You can then use any of the Inspectors (e.g. the WebForms Inspector) to edit the request.
