A few new features in 1.5.8:
Detailed totals by currency and exchange rate errors
Seems like the last update caused a lot of confusion related to how totals get calculated in Home currency. From 1.5.8 Financisto is more user-friendly and will tell if there is something wrong with exchange rates setup which can stop it from calculating correct total.
If everything is fine, then detailed total screen will show totals for every currency and overall total in Home currency.
Every report screen now includes Pie Chart button which shows, well, a pie chart for this report. This is experimental (does not work in Android 1.5 for example) and your constructive criticism is most welcome.
Exported .csv and .qif files can now be automatically uploaded to Dropbox.
