Redesigning transaction list for nostr:npub1getal6ykt05fsz5nqu4uld09nfj3y3qxmv8crys4aeut53unfvlqr80nfm and I have a question for you.
Does it make sense to differentiate zaps visually from other lightning payments (that also can have a message)?
My Nostr nerd side wants it, but my UX intuition say we shouldn’t do it. In a way it's just a "backend" for a payment with a message and I feel it adds unnecessary complication to transaction lists (looks dope though)

One slightly left-field suggestion...
Change the up/down icons to something that communicates the category of payment. A zap, or a podcast payment, or a purchase, etc.
You're already communicating whether it's an increase or decrease with the colour of the sats amount on the right hand side, so you don't need additional cues on the left. You could add a visual cue with a subtle background colour to that entry as well.
My (fancy online) bank does something similar.
We don’t know what payment it was for bolt11 payments so we can’t add categories there
