GUI - adjustments
Love the app but there are a few oddities that could improve the flow of the app.
1) you do not have direct access to the settings menu, with the new side shade, you can/ should put the settings in the Admin section
2) in "Customize Data" you should also add a group for re-fuel stations
3) on the Home screen you are wasting space with the "Export Button", please move that to Admin in the shade, and make the Re-Fuel button and the "+" button double wide for easier press
4) in the Plus button you are not using consistent naming with the shade. e.g. + "Car", but "Vehicles" in shade, and + "Reminder", but "Events" in shade.
5) actually I think having the + Car and + Reminder in the "+" button is a waste, as these are Admin activities. In fact you could replace the 3 buttons you have now (RE-Fuel, +, Export) with 3 buttons for Add Re-Fuel, Add Service, Add Expense (Bill).
6) In the sub menus of the Settings you are missing the < to get back to the higher level. You have it in the Settings to be back out but it is missing in "Units", "Data Backup", "Reminders", and "Advanced Settings". I know I can use my back button this is just about consistency.
