[KPhotoAlbum] Token setting in thumbnail view

[Johannes Zarl]

Hi,

Sorry for dragging this out. I haven't got much time for coding lately.

So just to be sure this is what we intend, let's do some paper test.

Assuming the demo database, with both "spiff" images stacked together, 
let's start with the stack in unexpanded state.

a) Selecting the spiff stack and pressing "a" tags only the front image (no 
surprises there).
b) Now pressing "B" stacks both images.
c) Expanding the stack, selecting only one image and pressing "C" only 
tags one image.
d) Collapsing the stack again, browsing to "All > fun", and pressing "D" 
tags both images.
e) Manually expanding the stack, browsing to "All > fun", and pressing "E" 
only tags one image.

Interaction-wise, I think the difference in behaviour between d) and e) 
could be frustrating for new users.

One possible solution would be to pop up a warning/info message when 
situation c) or e) is detected. Same thing for situation a).

Any more thoughts on this?

Cheers,
  Johannes
