I've just signed up and am loving the service already, but have thought of a few additional areas that might be helpful...
-Ability to add shares, even if they have to be tracked manually.
-Add savings targets and set due by dates for them etc.
-Add your own custom categories.
-Add something to replace the pie chart when viewing on an ipad. Even if it's just a simple table.
- Be able to click the monthly bar chart breakdown to show you the transactions that make up each label.
I think that's all!
