Perhaps, although I dislike the idea of having a seperate tool in this
instance - I think that transitions are almost as important as adding clips
themselves to the timeline, and think a solution that allows both to be
constructed with the same tool would be better.

Another possibility would be dragging an item from a transition dialog onto
the timeline, although from using premier, I find doing that a cumbersome
method of editing.

I am tempted by the idea that when one clip overlaps another, a transition
would be automatically generated. For this to work, I would envisage that
there would be an option on every track that said "auto-transition". Drag a
clip to one track, a clip to a second track, and if they overlap, a default
transition (probably crossfade, although it would be useful to let the user
specify the transition that they want) would be added. One problem with this
is that it would be quite easy to 'lose' a transition by accidentally
dragging clips away from each other again. Of course, it would make it very
easy to move clips around and try out different things :-)

In this case, I wouldn't mind a transition tool, as it would be for those
special cases where you don't want to auto-generate transitions, the most
obvious examples being picture-in-picture and scrolling text.

I am not sure that I understand what you mean - are to talking about the
same sort of automatic transition creation I am talking about above?
