This may be a bit controversial, but honestly the best feature for me would be if there's optional link to mempool.space from both the block and also the transaction view :)
Other ideas:
  • Currently there's (afaik) no way to get the full bitcoin address (it has "..." in the middle)
  • It would be great if the addresses in the UTXO are clickable, so I can navigate to those (it took me a while to find the ">" button to navigate to those)
  • It would be super cool if I can expand multiple linked utxos at the same time in a fullscreen view (I like that you use width to highlight the amount sent), e.g. if UTXO A was spent to B and B to C and C to D and E... it would be great if I can expand the UI to see all of this at the same time.
  • The transaction detail box takes quite a bit of space - I would prefer more concise view.
Great feedback, thank you!
Links to a more fully-featured explorer for additional details would definitely be useful.
The address truncation is actually only visual, you should still be able to copy and paste the full address if you select across both sides of the '...'
