Just thought I would share an idea to help make managing the transactions list a bit smoother.
As in email/messaging apps - swiping left/right on transactions to shortcut to a particular action. For me these would be change category and add notes. But perhaps this could be customised, others might prefer add to group/split/exclude etc.
At the moment all require a couple of clicks, and this would be a slick way to speed up the process.
