At the moment, to change the time interval of the chart, I need to return to the homepage screen, select the new time interval and return to the charts screen. It would be more convenient if time interval selection was possible directly in the charts screen.
In addition, by month comparison is not possible if you i.e. select a range from 2025-12-01 to 2026-02-28. It'll instead show a bar for each year with 2025 consisting of income/expenses of just Dec and 2026 of Jan+Feb (which usually isn't a useful comparsion). It'd be nice if we could manually select which intervals we want to be combined into a bar in the bar chart (year, month or week).
