Along with nice freebies like the shell extension to burn a VIDEO_TS folder with Imgburn I think it would be a cool utility to break out the menu designer. Just feed it a VIDEO_TS folder and it calculates the number of titles and sets buttons for each that you can rename in the menu editor thingy. It sure would come in handy for stuff that was re-authored to only contain desired titles etc..

Just a thought if you ever have this over abundance of free time, maybe 2 years from now or something.
