Surprising it took so long for someone to develop this. It works perfectly but from what I can tell, only supports one feed. I may be wrong there though. Beautiful and works well. And it's open source. Dev, please add a way to donate.
I couldn't set up facebook notifications via many ways. But this was as simple as that :)
No way to delete or to set days to keep notifications.
Simple app doing just what it is supposed to. Would be nice to have multiple feeds, but better not to over complicate it.
