Form (Adv) several minor requests

This form is insanely good! I love to design with the block editor, and now has so many possibilities! I have already implemented Form (Adv) in all the forms on my web pages. Can you give us these minor additions? 1) A URL input field (could be combined with the email field block). 2) Min/ Max number of characters in text field 3) Slider option in Number field – Range Slider 4) Possibility of adding an image/icon block in form The design of the success message and the error message needs improvement. There is no visual control of the text styling in backend, so it would be good to display a sample text below the form (switchable between success or error).
