Follow the example in the Wiki for "eachentrysaved()".
http://jwmusic.nu/jwplugins/wiki/doku.php?id=jwlua:development#eachentrysaved

Replace the inner contents of the example loop with "e.Visible = false"

Feel free to ask anything regarding script development! (Development 
should become much easier once 0.03 is available.)

That should NOT happen. I'm starting a timer to for buffering print 
output. Perhaps that timer isn't cleaned up correctly.

What operating system are you running?

You should be able to include any Lua package directly from the script, 
for example using "require". However, I haven't tested it yet and 
perhaps I need to set up some environment variables in JW Lua to get it 
to work well with user paths. To get JW Lua to work nicely with 3rd 
party Lua packages is a priority of mine.
