Changes:
I think I have eliminated the NaN’s (Not a Number’s) than could pop up. Also the main cost input box is more usable and stable. (no forever disappearing input box!)
If you have 0.7.0 you can just launch the program to be notified about the update (Thanks Palm (webOS) Update Check framework!!). Otherwise you can get What’s the Tip – Beta here. And as always your feedback is appreciated!
