add scrolling to multi view?

[adf-ncgr]

not sure this is a good idea, but I got the urge to try scrolling over just now and felt the lack. It seems like it would be possible to create a gene list based on the columns of the alignment, at least within a single group. you might have to fudge a bit if a given track had a "gap" in the column that would be the target of the next "focus". just adding as an idea for now- but I'll note upon a bit more reflection that you can more or less approximate the behavior by using the gene family -> ~~pan~~ multi view, although this does not include the "fudge factor"
