Fixup Legacy Explorer

Devils advocate here, does the time investment warrant keeping the legacy UI around vs implementing this as an enhancement to the timeline UI? Especially since I feel like the UI in general is probably the biggest thing to work on next after initiatives (Summary of planning chat).

And nit for “Status: Championed” I’m not sure what this means exactly other than what the next section tells me (“Champion: @decentralion”).

How about, status planned? As opposed to proposal or not started, combined with having a champion, I would think this means the champion has committed to doing this work, though hasn’t started.
