The tagging should be very easy. You just select a region (just like the
default crop in showFoto) and you tag it by dragging a tag over it or then
applying a tags. 

If user has not a region selected, the tag is placed for whole photo. 
If there is region selected, tags are for that only.

At least the face tagging should be with Ctrl+Drag way. Same way as user
selects area from the Marble. This is one problematic because the area
selection is needed to be similar on all digiKam views, it is a usability
question. This was one point for having a Ctrl+Drag for panning view in
preview. Because we needed just the dragging for tagging. But now it is needed
to be a Ctrl+Drag.

In showFoto the dragging already creates the selection for effects/cropping,
without a Ctrl (etc). It already forces to be different way in showFoto and
digiKam preview (+lighttable). So it is needed that showFoto, digiKam and
Lighttable all use Ctrl+Drag as selection for region, what then will be used
for tagging, cropping and effects.

That selection function could be possible to linked after summer (or same time
with someone else) with task to create a brushes function. For allowing a
clone/heal stamp, layer masks or other local non-destructive editing (but those
would be a circular selections while we now need a retancle.

I would vote to the 1:1 format because it is easy to be used then anywhere else
when there is no need to take care of possible different format. It could be
used as tag screenshot, album screenshot, screenshot in other places using
nepomuk etc. And it would stand better ways in use the cropping and other
functions. Easy to drag a area and show all different area-tags in next each
others when they are same format.

The sidepanel where the face tagging should be placed is littlebit harder. Now
we have a tag search on left and tagging on right. Some people does not like it
and would like to mix them. But it would remove powerfull functionality from
digiKam. Right now because of left/right separation, we can search by tags and
then remove/apply tags from search results. That is something what is not any
other photo management application offering so easily.

So would the face/area tagging need a two different tabs more? I believe we
could link the area tagging for the tags itself. But add only a new tab for
face tagging.
We just dont change tags in faces as much as we can do with subjects in photos
otherwise. Like if we edit photo, we do not change character face tag to "John
Doe" > "John Doe Edited". But we might add new tag "Edited" or "Print version"
to it. 

So is there a need for two sidepanels for face tagging? (Search / Tag)
