I had an idea for a feature request that's probably best to go into Validator - although it may be better as a feature request for WME itself, let me know what you think. I hope I can explain it coherently enough.
I'd like to see hyperlinks on the sidebar when a segment is selected and one or both of its endpoints are "off screen" (i.e. you're zoomed in tight enough that you don't see the entire segment). The hyperlinks would be displayed as "Jump to node A" and "Jump to node B" (appearing as necessary, i.e. if node A is on screen, it doesn't need to be shown). When clicked, the map view would recenter, at the same zoom level it's currently at, to show the node being referenced. The entire segment should remain selected (i.e. don't just select that node and display it).
This idea came to me when looking at a 17,000+ meter segment in WME that Validator had highlighted, and I was zoomed in somewhat tightly on node A, and the Validator info said "Unconfirmed turn on node B". Rather than zoom out, recenter, and zoom back in, or scroll a huge number of times to find the B end, I'd like to be able to see that other end with just one click.
