Thanks, gonna look into that link.
Yeah, it would be some way adding this function to PopUp but in this moment i feel how painfull it would be to configure it and disable everything in PopUp menu to have only toast notifications. Having two separate plugins would be easier to manage what kind of notifications you would have. Of course it's possible to do that also inside of PopUp, but i'm not sure if time spend of coding this inside existing plugin would be same or less then in separate plugin.
