Hi Chris,
Thank you for contacting us. Unfortunately, the UI you are referring to here in Safari and Firefox is not able to be altered in any way. It's functionality and UI offered to 3rd party developers by Apple, and they do not give us any way to change the way it functions.
We believe there are options for creating our own Browser Extension for iOS, which is something on our radar. However, that's something we have to prioritize for an upcoming release in that's it's not simply making changes to already established UI. We have to develop that functionality from the ground up, so it will take some time to implement.
Chris
