Okay, so you want the "Go to first song after m_lastindex that matches
the pattern/type/casematters and play it" function.
Excellent. Now there is a clear plan: have both a "return all results
as a playlist" and the above solution. The playlist is much more
complex, so first create the function that the console needs.
Here is a question to all:
For the pop-up search window I discussed before, what would be the
best design to allow all platforms to have the same thing? Try to
be specific.
