If a file is opened but cannot be parsed (e.g., an SQBS data file that was mislabeled as a YellowFruit file), currently nothing visible happens, the file is simply not opened. An error message would be better.
In some cases (opening in YellowFruit v3.0.2 a file that might have been generated by or for YellowFruit v2.5.4?), the app goes to a white screen instead.
