wnck_screen_get_default() in panel plugin

[Simon Steinbeiss]

Hi,

to get a bit more context - where's the code for this plugin?
To be honest I don't know this plugin, it's not on git.xfce (which doesn't
mean it doesn't exist ofc).

Also in terms of the functionality I don't understand why this is
implemented as a plugin to the panel and not a simple standalone service.
There's no need to see the plugin at all times in a panel and the
functionality isn't related to the panel at all...

Cheers
Simon
