very nice and most usefull! I'd loce to see a way to change the databse location though: I keep my stuff syncronized elsewhere than /home/user. It would be nice to allow editing with a double click..hm..double tap. Also would be usefull to check the date and entered kilometers - I often find myself typing old gasoline purchases or repairs and always end up re-editing the row - as the date defaulted to this current date (check where the mileage fits in current db and whine about it)
it would be nice to be able to report services as well ;)
Anyway this it app to the right spot!!! Thanks a million!

To Erkka: You can change the location, however there is no user interface for doing that. There is a reason why it isn't available and I don't recommend changing the location unless you really know what you are doing.
