[Digikam-devel] People tagging design

[Alex Jironkin]

From usability point of view having an extra window that does the same job as preview, but draws rectangles and writes names, is a bit annoying and personally I think should be avoided at all costs as it will make digikam bulky. 

If we can't bring detection speed to something manageable, on my dual core it takes 2.5 secs but not everyone has dual core, then I think Michael's idea of adding extra tab on left side is a very sensible one. Perhaps that is also where found/known faces/people should go too.

If we knew what we were doing, it wouldn't be called research, would it?
