Glad you found that useful. I now see your open issue on Blockchair GH... good news is that it seems to be a recognised bug and you'll have made the fix possible! I haven't had the opportunity to truly use all the explorers out there but Blockchair's pretty much the best deal to me for native SW support... which makes me wonder if those others I mentioned would have caught up.

Lightning analysis will be even more interesting I think, though there's already some explorers like 1ML and LightBlock - admittedly with very basic analytics atm, don't seem to see groupings by input available.
