Hey caco3, great update on the user interface. I have a couple questions/requests:

1-) Do you support old csv records? It seems the headers are also updated which record viewer can no longer open them.

2-) When I choose "Set Alarm and start recording" (you can lower-case Alarm) after setting the alarm the record window shows me a big loading on the canvas but doesn't disappear. A bug?

3-) Show additional information title is truncated. You can simple replace it with Additional information or "Sleeping statistics"

4-) You can add combined statistics for all sleep data instead of only one record.

My version is 1.6-47. Thanks for this nice app again.
