I often see transactions whose descriptions on my statements are cryptic (eBay, PayPal), hard to remember (is that the name of a restaurant?), or complicated (an erroneous charge or credit to refund it).
A pet peeve in my banking app is not being able to add a comment to a transaction to help with reconciling, checking, searching, explaining it. Ideally the first 20ish characters of my comment could appear below the transaction description in the middle of the transaction list, so I don’t have to open the transaction detail to keep checking.
If Snoop would let me do that then I think I’d use Snoop more than my banking app (a win for me and a win for Snoop).
