It would be great to have the ability to track bitcoin transactions/balances outside of proton. For instance, if someone is running a bitcoin node and using Sparrow Wallet, we should have the ability to add the xpub which derives all the possible addresses used to see the balance and transactions of bitcoin. I like Bitcoin Wallet, but the limitation options with it does not make you want to put too much in it. If contacted, i can provide a screenshot of what other wallets would need to track the transactions/balances. In this situation, we don't need the seed phrase. This is just to track as a read only, not to actually transact.
