Interesting. That however could lead to other complications, e.g. that potentially the tx fees would be listed twice (but only paid once).

Could your problem maybe be solved in other ways? For example, make the notes field multiline so you can enter more elaborate notes.

As it's about incoming transactions, there is no fee.

If the notes belong to the output address instead of the transaction, that could be an option. But I can't imagine how to solve this in the UI. From the UI perspective, I still find it more intuitive to have one "transaction" per output address in the transaction overview, as it is in the export.

How did I noticed this issue? I withdrew from an exchange to several addresses with the intention to write different notes to them, as soon as the transactions are visible in the BitBox-App. But as the exchange used one "bitcoin transaction" for my several "transactions", there is only one "transaction" in the transaction overview.
