I am trying the Peakto 1.0.8 right now with my apple photos library (97 000 pictures > waiting to migrate into capture One) and some messy folders (60 000 pictures).
I was expecting to organize them adding some keywords but it looks like we cannot. Would you plan to add a layer of keywords? Even if they are only viewable into peaks, that would be in order to complete the ones or add missing ones (especially from folders). It would make the organization much faster.
Also, it looks like wa can't select / copy past metadatas from the inspector window. That is a pity because we often need to it to search again and organize.
