create multiple smart mode buttons

I'd love to be able to add additional smart mode buttons (Create New Smart Mode), where I could specify different things. Maybe have one that just grabs the highest quality video as is, one that only grabs a 256k MP3, another that downloads the highest framerate version of the video, and maybe another that downloads 480p with subtitles... Whatever setting you choose.

I frequently have to turn OFF Smart Mode, so I can specify a different set of download parameters than what I typically use, then have to reset my parameters and turn it back on.

You could select the active Smart Mode by simply clicking it. clicking it again would let you change the settings or delete it. When only one smart mode is active, or it's shut off, it would act as it currently does.
