How can we improve WHMCS?

Right now we have an annual income report which shows month over month with the current and previous 2 years. What would be really nice is to have a year over year income (line graph or bar chart) so we can see where our best income years were and do business planning/sales forecasting based on that.

It would look a lot like the current annual report but the bars would be years instead of months. I have yet to find a custom report out there that does this. The current report you have to click the years at the bottom and write it down then enter into a spreadsheet to chart it. Would be a HUGE time saver to just have a report!
