By the way I really like how photo supreme was designed to handle so many details about metadata and make things simple.
One feature I like is the relationship between 2 keywords, I think it would be interesting to expand this functionality and maybe modify its behavior.
Expanding it: It would be great to be able to nest relationship under some folders. For example lets take a person label:
- Jack as friend
- Elsa as best
- Jo as colleague
- Dani as son
- Domi as daughter
- Jule as great grand son
- Helen as grandmother
- Ben as Father
Because when you try to do that with many friends and family member the usability of the function is overhelmed by the number of entries.
The second thing I would propose is a behavior modification:
Today if you click on John you will display all the photos with John -> Great
if you click on the Jack entry that sits below john (displayed as john's friend relationship type) you will then display all the photos with Jack -> I would change that so that in this case you display all the photos with John And Jack. I think this makes much more sense because if you want all photos from jack you can already display it by clicking the "main" jack label. If you dig down to jack thru John I suppose this means you wanted to see them both.
