           Summary: focus textbox for identifying faces gets lost too
                    easily (and other issues)
           Product: digikam
           Version: 2.0.0
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Face Detection
        AssignedTo: digikam-devel at kde.org
        ReportedBy: s.oosthoek at xs4all.nl


Version:           2.0.0 (using KDE 4.7.0) 
OS:                Linux

When identifying faces, it is a lot of repetitive work to identify every
unknown face. This work is made even more difficult by the focus and selection
behaviour of the textbox for typing the name for the face.

Currently the focus seems to follow the mouse in unexpected ways. So when I
swipe over the current (automatically filled) tag to change it, the focus on
the box gets lost as soon as the mouse leaves the box area. This is unlike
other textboxes which remain focussed when being used. (BTW, I'm so used to
selecting and overtyping to change the text, that I completely overlooked the
<x] thingy at the right of the box...)

I'm sure there are lots of ways to improve the usability of the
face-identification, because it is a lot of hard work to do right now.
As example, I scanned my limited collection of about 20 months and got around
2000 unknown faces. Most of these represent the same faces over and over, so it
should be possible to group them based on similarity (that's what it does
anyway, when looking for faces, right?)

Another problem is the fact that I shoot RAW+JPG and this leads to mostly
double the number of faces found, since each RAW and each JPG is a different
image to the detector, it seems.

The check and minus signs also come without any explanation. They seem obvious
at first, but a small hint in a tooltip could make a big difference in
usability for new users. (Check adds the tag to the face, minus says: this is
not a face? or something else?)

It would also help to select multiple images and identify them at once.

Undo the identification would help correct mistakes in the identification
(easily done when having so many repeating clicks).


Reproducible: Didn't try

Steps to Reproduce:
have about 2000 faces in unknown for about 20 people and 50% of one person, 30%
of another. Start identifying them and use the swipe select method to change
the tag below the image.

Actual Results:  
focus gets lost easily

Expected Results:  
focus remains in the textbox after selecting and for the rest: less manual work
to identify faces (that's what face detection is intended to improve, I think).
