Fix rBrowser 2.0?

I love this who ever made it, but I need to change some stuff or else I will go mad trying to use it.

In the sound browser, when you double click a file, it plays, but if you double click another, this one will play on top of the other sound. I want it so that when you double click another file, it closes out of the sound panel and stops the previous sound, whilst playing the sound you just clicked on.

And, when you copy a sound file, it looks like this “sound/blah/blah/blah.mp3”
I need it to not include the “sound/”

Anyone, this can’t be that hard?

Here is the download for people who want to attempt this:
