Properly handle file paths with spaces for @'d files (?)

What feature would you like to see?

I'm not sure if this is currently working properly or not, actually, because it's difficult to evaluate, but I have many file paths I reference via @ which contain spaces and I worry this degrades the model's ability to understand what I'm referencing.

It would also be great if the TUI could highlight these paths like it does usually for images I drag in, to help confirm this is working properly... Could be the only solution needed if spaces are indeed fine, to give confidence it's working.

Are you interested in implementing this feature?
