I've acknowledged, that there is no way to extend selectively metadata showed in detail-view besides few available informations. What about limiting few that are showed in default.
My problem is that informations like date of creation and modification of file are pretty useless to me, but take some space in Content Panel forcing me to stretch it and to minimize panel with the image view. I'd like to see keywords under rating for example. I'm managing large number of science related photos. To describe it using keywords i got to see image as large as possible in horizontal position. Minimizing other columns would save a lot of time.
Opening metadata panel takes some space either (and also - info refer only to one img at the time) so it's a missed sulotion, and i'm still not so good at script writing so it's not possible for me to solve the problem this way (yet!). Is there any other way?
