I very much hope we end up with something like what is being tested, so that we both get a better visualization of #panoramax image coverage (hex grid is so much better than the old dots grid), and some way to display raw sequence lines.
I rely on seeing the sequence lines when planning routes for where to capture next.
One limitation with the current format is that you can't see lines from other instances. This is a problem if images are well split up between multiple instances.
