Currently, there are a few options for Smart Links:
URL - Raw URL
Inline - Favicon + Page Title
Card - Inline + Description
Embed - Page Preview

As it is now it's not possible to modify the formatting or end result of the Smart Link. This is a request to allow customization of these such as through CSS or simple options.

eg: A user should be able to set inline to "plain text" styling or effectively disable favicon & boxshadow/border display &or change color, size, etc. of how it displays
