When I set maximumEntries: 8 I only see items 3 items.
I did some testing and I think the reason I only see 3 items is because some items are excluded.
I think the excluded items are counted as well.

I’d like to have absolute days in my calendar, but all I see is ‘today’, Saturday (without date), etc.

My config is:
maximumEntries: 8,
useRelativeDates: false,
joiningWord: “om”,
maxTitleLength: 48,
dateFormat: “D MMMM YYYY”,
timeFormat: “HH:mm”,
urgency: 0,
getRelative: 0,
calendars: [* secret *]

Am I doing something wrong?

Some things like timeFormat (HH:mm), maxTitleLength and joiningWord work fine.
