Most day-to-day entries are income or expenses. Scrolling down every time to pick the type in or ex is a bit of a pain. Instead of bumping up those 2 types to the top of the list I thought of a better idea...
What if the type list was sorted and updated as per your last row selection? This could make the software more user friendly and increase overall transaction entry efficiency.
For example. You picked expense for a type, the account and entered an amount. When you add a new row the type EX would show up at the top of the list and you could simply hit the space bar twice to pick it. Something along the lines of this would definitely help improve the user experience.
