Add an extra dropdown for showing invalidated times (by mapversion) and possibly one to compare records regardless of map versions as well. Ofc only where relevant.
And handle it in the record view for tabs too..
Finished. It's the new dropdown select in the sidebar when looking at records for a level. :)
I think all maps are ok, but there could be some weirdness with a few I haven't checked. So let me know if you encounter something.
