It would be nice if you could drag and select a region to zoom
in on, so that bounds control of the new zoom area is precise. The
UCSC Genome Browser has that feature and I use it a lot. You can
click and drag on the coordinates line, and a blue box appears that
clearly delineates the new view that you will zoom to. It is very,
VERY useful.
This may conflict with the click-and-drag to pan feature. Right
now, you click on the coordinates bar to drag the view around. I am
asking that when you click and drag there, you define a region to
select. I think maybe the click-and-drag by the coordinate bar can
be disabled -- after all, you can drag by pretty much any other
part of the view -- and its function (other than display coords)
would be to draw a view selection on it.
Granted, you could say that JBrowse's fluid motion allows you to
reposition the view much more rapidly than UCSC's browser, so this
feature is not needed -- you can just zoom and drag around a bunch,
and if you really must, edit coordinates by hand. However, I
disagree. I frequently like to select areas specifically containing
exactly one gene, or gene region, that I identify for a further-out
zoom. Being able to precisely define a region to display visually
would be very nice.
