# Use "Extensions > Export all" in the desired channel and category,
# to export all station entries at once. Currently just export PLS,
# which in turn references other .pls file).  Luckily most players
# Adds a context menu "Extensions > Export all", which can be used
# in any channel and category to save all stations into one playlist.
# Defaults to exporting as .PLS file, but meanwhile can be used for
# XSPF or old M3U files as well.
# Note that a .desktop link can only hold the very first entry.
#
# It won't convert the internal stream URLs though. Such that the
# combined playlist file may reference further playlists from servers
# can cover up for this horrid misdesign.
# of a directory provider.
#
# This is a workaround until the main GUI supports selecting multiple
# rows at once, and the action.* module has been overhauled to export
# rows at once. You can already save as
# a bit more deterministically.
