A click in the Overview box immediately shifts its left edge to the
mouse position (also in 2.10.1 so no change there).
To me it would be more intuitive if it behaved like a cursor bar,
i.e. didn't move until you dragged it.
As it is, it is impossible, or at least difficult, to make small
adjustments to the position using the box.
The cursor bar analogy confused me until I read your whole email twice
(and composed a complete response..). I agree it would be better if a
click inside the visible area only adjusted the view position when it
becomes a drag (and that the drag delta is applied to shift the view,
rather than using absolute mouse position). New issue is here:
The click-drag view range model dovetails with Albert Vilella's
excellent feature req https://issues.jalview.org/browse/JAL-232 - which
is part of the Overview panel's roadmap. We need to thresh out the
details, but essentially, the overview panel will become the primary
means of interaction when working with very large alignments, and could
be used for view creation/deletion and navigation between views.
This is for a relatively small alignment, with a relatively wide
Very big (genomic) alignments have a skinny box, except when showing
a hidden region (intron), so the problem doesn't arise.
Skinny/ultrawide boxes are another issue We need to think about the
situation when a view is one pixel high in the overview (I've started to
document this via a user story here:
I would leave "click outside the box moves the box" as it is.
I think it needs fixing too. The 'clicked point becomes the top left'
behavior is - to my mind - wrong: most bird-eye views in other systems
do not behave in this way (try illustrator, gimp, photoshop, etc...) -
there, the clicked position becomes the **centre**, not the top-left of
the newly positioned view. I'm very much open to discussion about this -
but I personally think it would be an improvement if we switched to a
'click centres view' model. Issue is here:
