Well it might be more than just a feature request.
Think along the lines of wireshark, you can separate out the underlying code to do the work in a library, then use that in a cli and gui. If you're working on a cli app yourself, that "feature request" might hit things you just don't have the will to do. I know me making any sort of gui is going to end up a tire fire, and the work to cleanly separate out the code from the cli to a library usable by both is also a bunch of work for what appears to be a at best nice to have "feature".
