Don't see how to set severity on bugs logging them on GitHub, but I'd rate this one Sev 4 or 5. As you can see in the picture, when you select a trail from the pull-down to use, it overlaps (behind) the Users pull-down list label. You can widen the browser to make this fit, but it should probably be set to enforce a scrollbar or the lists should stack vertically to avoid this or something. Purely cosmetic, but the formatting makes the UI look a little haphazard and sloppy.
