Move closer to the original vision of supporting any address-querying implementation desired. Current options include ElectrumX (as before) and now blockchain.com and blockcypher.com since they were easy to support and are publicly/easily available (though ridiculously neither is yet to support bc1 addresses).
- new env var option BTCEXP_ADDRESS_API, value can be electrumx, blockchain.com, blockcypher.com
- update ElectrumX client connect to request v1.4 of API as all clients are now supposed to do
- misc frontend improvements/cleanup for addresses
- footer: full-width to match header; remove bottom border
- extraneous padding removed from some tx lists
- fix some card-body wrapping issues for paginations at bottom
- bold text for selected address in tx-io-details on address page
- hide large # of outputs by default on address page, only showing default 10 + all outputs for the selected address, with link to show hidden outputs
- table responsiveness improvements
- add some shadows for visual depth
- hide radial progress bars on small screens since they're not working properly
- text-wrapping improvement for addresses in tx io details
- in tx history, request/display all inputs to get correct gain/loss values
- cross referencing for txid history from electrum
- include genesis coinbase values for genesis coinbase output address (electrum ignores the genesis coinbase TX and +50 value, but for consistency with the rest of this tool they're included)
- banner describing the electrum trust model
- ui tweaks including showing gain/loss for each address tx history item
