Gregory, is there a reason why the long-lines-improvements branch is not yet merged? I think it already includes important improvements that should be exposed to a larger population for testing and feedback. If you for some reason prefer to keep that branch active, can you please merge the current master to it, so that the changes in narrow-to-region will be on the branch? As things are now, the problems you solved on master in that part are not yet solved on the branch, and so working on the branch runs the risk of hitting problems unrelated to changes in display code. Thanks.
