I would love to see an option on Sfile so you could select multiple files (or a $sfiles function).

With the ability to select multiple files (like you can in windows when selecting files).
The results of the new function would be passed back as a comma separated list.
The list returned could then be tokenized and used it to add songs to the /splay queue.

KeiroD has an example of how to get around this issue in his music player script.
But it involves using a hashtable, adding to it, writing the hash table , and reloadeding the hash table to generate the playlist queue.
I feel a way to tag multiple files via $sfile, would be easier to work with.
