Eventlist is a KDE Plasmoid that shows the events from Akonadi resources. There is already an ebuild for it in the KDE overlay and it works (it's only a bit dated) It would be nice to see it (updated and) in the official Portage tree. Reproducible: Always
I tried locally bumping the ebuild (from 0.3.97 to 0.4.95) in the KDE overlay and it works just fine.
Added to the main tree, enjoy!
