We need the ability to sort transactions by multiple criteria. For example, sort by date first, then transactions that have the same date could be further sorted by payee or amount (or whatever column the user chooses).
It's confusing to see a list of 20+ transactions that all have the same data for the sort criteria and then are lumped together with no apparent logic. If all my weekend transactions post on Monday, I'd like to have an easier way of viewing them rather than scrolling through the list and likely missing the one I'm looking for. Adding a second column to sort by would allow me to fine-tune my budget processing and make sure no transactions are missed.
Multilevel sort is not only an essential feature, it should be a basic consideration for a paid product.
