Hello everyone,
I've just migrated to Kubuntu 15.04 including the shiny new KDE 5. It was a pleasant experience except that I can't find a way to tag and rate my pictures anymore. Rating (with the stars) is the most important for me.
My previous ratings are still there as they are displayed in Dolphin, but there is simply nothing in Gwenview regarding ratings... The information panel on the left is nearly empty.

I tried upgrading with the backports PPA but still no ratings.

Any idea ? I might downgrade just because of this :/
