Finally got to install this. I'm poking around it now.
So far a quick couple items:
I'd change "Arcade" to "Video game" in the type pulldown in the grey area. Here "Arcade" can refer to anything found in the arcade regardless of type.
In the Contacts there should be a column for State if possible. In the US contacts generally have a city, state, and zip. This only has the city and zip.
In the Find machine screen the sorting doesn't do anything.
Nice touch on the "do you want to save the unsaved data" dialog before changing screens. If it's not retaining that when you switch off that would be a major headache.
