We would like to have more capabilities under Form settings> Submission> Post submission actions> Thank you notification / Error notification (the pages that display the “Thank you notification”/” Error notification” sentences and the icons next to them):

1.     An option to replace the default icon with an image of any size, and in different formats (JPG, GIF, PNG)

2.     A richer text editor with multiple lines and not just a single sentence, with control over the font, size, etc.

3.     An option to add an editable button with similar capabilities to that of the button in the form including adding a link
