About to 2 years ago I wanted to develop an application like MMEX (in Java or C# - I'm a Java developer) because I wanted a (free) simple personal finance software with some basic features, user friendly, etc. Then I found this app...
I've been using MMEX since then and I'm quite happy, but I always missed one feature. Cash Flow Forecast being limited to 12 months is a little annoying, there should be an option to forecast more. So I decided to get the source and take a look.
The idea is to click in the Cash Flow option and a dialog pops up and asks for how many years do we want to forecast. We choose between 1 and 5 years (looks reasonable) and then the report is shown. I attached 2 screenshots to show what I mean.
If you think this is interesting and want to include it in the app, I can provide the code (bear with me, I'm a Java developer

Cheers
PS - I have other ideas to the app, including another cash flow report with a calendar view.
