Implement an unbounded capture mode


In older versions of the software you could simply start a capture and then hit enter to stop it when you're done. It would be nice to have this functionality again rather than having to guess how long you want your capture to last when you start.

This is especially handy when reverse engineering devices where you need to physically manipulate things.

I can't figure out how to do this in the 'newer' software, I'm currently on 1.1.23.

This used to exist in older versions of the software
