A plugin may well call Skins.Message(), but only from the _main_
I'm thinking about a function like
which would be called in every turn of the main loop (i.e. from the
foreground thread) whenever there is no OSD display open. A plugin
could either return a cOsdObject that will be presented to the user,
or could directly display a message (even with user interaction, if
necessary) and retrun NULL. Of course, if a plugin's thread wants to
issue a message, it will have to store the message inside the plugin
and wait until asked through a call to its Popup() function.
Would that be a useful solution?
