We already have drag and drop to import ROMs the option to import ROMs from the tools menu and you can click add in the bottom right corner to add a single game. I'm all for redundancy to do things it happens to be one of the things that I love about Windows but how many methods do we really need. That said if it isn't hard to implement, wouldn't take up much development time and other users liked the idea then who am I to say it shouldn't be implemented.
