True. I still haven't looked into this one yet, though. Marcel, how can we
detect if the RAW + JPEG are actually a pair? By filename is not enough, so
I suppose by some metadata, right (because the camera itself also display
the pair as one image)?

As someone already proposed, two buttons in the sidebar would be great if
we're working with versioned image - Assign only to this image / Assign to
whole version branch (some better captions of course) - otherwise display
one like now. I'll implement this. Should be fairly easy.

Yes, there was an idea for that, but I dropped it later, because of
switching the images. If you move any image from the relation anywhere else,
you still have it in the sidebar among the available versions, but you can't
switch to it, because it would need to switch the album as well. Also it
would break the concept of "current-version" that we had back then. Now when
you can have more than one "current" image, it could be done I suppose.
Actually, this could also be achieved kinda easily. But - What do you think,
is switching albums ok? I mean you select a version from the sidebar which
is not in current album, so the album will change and you will have selected
the desired version. I'm just afraid that this could seem a little chaotic
to some users (suddenly all the pictures are gone and they see some bunch of
other images etc).
