thank you very much for all your comments and suggestions. I'll make a post about them right after this one.
This post will only give a quick overview of v0.7.2 enhancements :
- now you'll have a warining message before deleting several items at the time (piggies, expenses, ...)
- the softkeyboard now displays automatically when you reach a screen with fields to fill. Tell me it does not work on some fields.
