I use the budget feature quite extensively to track and manage spending, particularly the view that shows me how I perform against each category.
However once the new pay day month begins, it resets to the new month and you can no longer view how you did against the previous one. The report you send isn’t as good as just seeing it. Budgeting is the sole reason I use Emma, so would be good to see this added to made it a bit more robust. (Unless I’m missing something and it exists 
)
