For most DSLRs there won't be such stitching mode
because there is no live-preview (apart from those who
already have  a 1D Mark III ;-)

Usually takes such pictures in manual mode
(after selecting exposure for one direction) and with a fixed
white-balance. So this, together with specifying a time-interval
(i.e. shots taking in a range < 1 min.), should allow
automatic grouping.

Yes, for the to-be HDRs (which I still have to process ;-),
my Canon 350D records:
  Exposure Mode: Autobracket
  Exposure Bias: 0, -2, 2       (in that order)

So it is straight-forward to sort them into a group.

> This could be an hint for Digikam to group the picture (later when the 'group of pictures' is implemented) and add actions such "Stitch using Hugin." "Stitch using "qtpfsgui".


Yes, grouping of pictures would definitively help a lot for such
of tasks (including the possibility to select more than one
representative image of such a group to be visible in the album view etc.)

But for this, a change in the database would be necessary +
adding quite a bit of code ...

Hmm, all this is more related to
