If you want more suggestions,
- Chain size.
- Blocks until next difficulty.
- Blocks until next halving.
- Hash rate.
Proud to be a Bitcoin geek.

Thanks, those are great suggestions!
I believe I'll split it up into multiple screens then:
Blockchain Data
- Block height
- Bitcoin mined
- Blockchain size
Mining
- Blocks until next diff
- Blocks until next halving
- Hashrate
Mempool
- Size
- Fee fastest
- Fee medium
- Fee slow
Price
- USD per coin
- [insert other currency] per coin
- sat per USD
- sat per [insert other currency]
Lightning
- Capacity
- Number of channels
- ...
It would become tricky to set a useful speed though; if it's too fast, you can't read it in time and it is distracting. If it's too slow, you can miss milestones like the 19M BTC (it was fun to watch it live!)..
Maybe I'll just try to get my hands on 2 more panels..
