Feature request: Option to fit ftb input box to width of clozed answer

[LuneAria]

Basically what it says. I was hoping for instance if the clozed word was something short such as "cat" the input box would automatically shrink in width so only about 3 letters would be contained. A longer word like "banana" would have an input box of greater width. That way cards would look a lot neater as the text wouldn't jump everywhere to fill the blank space when an answer is inputted.

Thank you for your work!
