when I first used this addon I found it very usefull. Until it started showing notification popups. There was no way to discard them, they kept coming. Apparently I should pay a contribution to get the 'delete' icon turn from grey to black and make it active. So I payed. After that the delete icon disapeared all together. So I got stuck with ongoing notification popups from events allready passed. I reinstalled several times, without result. Then I discarded the thing. I payed for 2 PCs. On both I got the same problem.
