So I contacted the dev of the amazing site/app Timechain Calendar on Twitter a few months ago (I forgot his name/username now and I'm doing #MarchOffTwitter) and asked him if he'd possibly add that to his app. He said it sounded like a good idea and he put it on his roadmap. No idea if he'll actually do it or not but it would be amazing. It's also what I use to guesstimate what block height a future date/time will be. But having that all at your fingertips would be amazing!!

PS: Having a BlockClock really helps with always being aware of the block height too.
