13 years ago click and drag to select a zoom region
Oops, I think this is a duplicate of features requested in tickets #42 and #21 -- if so, this should be closed or deleted or something.

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.
