@Djtux Thanks for adding the calendar features to the scanner, it was very useful!
You've asked which additional columns we would like to have, so here is my input:
As far as I understood, the current setup of the scanner allows to scan 'standard' calendars only (number of weeks: 'Auto' and earnings type: 'After'). I think it would be nice to be able to scan all possible calendars (weeks 1-5, earnings 'Before' and 'After'). Thus it would make sense to add two more columns to the scanner: 'Number of weeks between the calendar legs' and 'Short leg expiry before or after earnings'.
