You nailed it here. I've been waiting for something like this - Mint etc. don't give me enough functionality in terms of forecasting, seeing a trend and helping me to modify my behavior.
If you could also add a "Simulate spending X {currency} on YYYY-MM-DD" type functionality for forecasting, that would be huge. This was something I miss from one of the old Microsoft Money desktop apps, and being able to see how making a purchase at a point in time will affect you 1 week, 1 month, 1 quarter down the road etc. is a powerful deterrent to impulse buying.
Upcoming expenses is a great idea, and was an original feature from my own budgeting spreadsheet but has not made it as a feature yet on Lunch Money. Your comment definitely helps boost up its priority :)
