Recent Global Posts with Multiple Widgets instances?

Hi,

I'm testing Recent Global Posts plugin and it's very powerful. But we can use the widget for just one sidebar. This plugin doesn't seem to run with multiple instances.
I've seen some tutorials on how make a plugin running multiple instances but I don't really see how I could apply this for this plugin, this requires too much knowledge of developement for me.

If someone see what code we could replace to make this widget available for many sidebars, I'll be grateful for this. Or maybe an update is in project but it doesn't seem to be the case,unfortunately.

Thanks if you have some clues
