The dots red, orange and green indicates the status of the item described - more or less as a traffic light:
Red = initial (the item is simply recorded)
Orange = in progress (some information of the item are provided)
Green = completed (the description of the item is completed)
In the list of collections there are two dots:
beside 'code' it indicates the status of description of the collection (i.e. whether all the sermons are recorded)
beside 'editions' it indicates whether all the editions of that collection are already listed
In the list of sermons the dot indicates:
red = the entry is limited to the thema and the liturgical day.
orange = there is also the main division or a few basic information
green = there is also a summary of the sermon
