For customers of a shop:

- bitcoin price

- Expenses for the products in bitcoin (transactions but only the amounts)

- a nostr portal regarding the latest developments

- average fees

- who mined the block

- donation address

For personal use probably:

- searching my own transactions

- bitcoin transacted and how long they were hodled

- miner pool

- orphaned blocks history

- difficulty visualizer

- utxo.live graph, but not linear

- amount of miner income

- block hash

I probably also want some visualizations to be as as closely resembling the raw block content if possible.
