Well, if we would go to plurals, it would be wrong the other way if there are only single entries . Also, I think the properties don't have to plural, they are internal. The labels of them should adjust for the singular or plural case. That said, I don't think we can achieve that without breaking the programming interface, so we're stuck with that. >> To be honest, I don't know which tooltip you mean. Can you post a picture?

Looks not so nice with lots of entries. Imho there should be a maximum number of properties, and a scrollbar should be used if that threshold is exceeded.

A screenshot of the dialog would be nice (large enough to display everthing). The infopanel looks perfectly fine: F5736838: Screenshot_20180302_204919.png <https://phabricator.kde.org/F5736838> >>> 1.

We should not repeat that, if possible. I agree that we should think that through. Once committed, we're stuck with that for the time being. In this specific case, I would actually argue that the conductor and director are different. Imho there is only limited potential to find tags that work for everything. Video, Music, text etc. are different after all. > The property names are important for searching with baloo. Everything comes together here.

This is not the place to discuss that, though. I haven't this much thought yet it's just a feeling we might get into trouble in the future. We pretty much have to cope with whats available out there in the wild as de facto standard. We're only consumers here.
