In the new Budgeting tab, you can sort payments per category at the bar graph. When you spent more compared to last month, it shows a red (negative) arrow up, else it shows a green arrow down (positive). - Makes sense so far.
However, when I set the category to 'Income', it pretends it's a spending. Meaning that it has a green arrow down when I earned LESS, and a red arrow up when I earned MORE - meaning bunq is saying its a good thing I made less :-(
Minor thing, but thought it would be nice to report it :)
