A diary that has been running for a year can hold hundreds of entries, and a page that renders every one of them is slow to load and hard to read. The Entries per page parameter caps how many are shown at once.
Setting a page size
Choose All, 10, 25, or 50 in the macro configuration — see Macro Parameters. All is the default, and never hides anything.
How More works
With a page size set, the Diary shows that many entries and a More button underneath. Each click reveals the next page of entries below the ones already on screen.
📷 Screenshot: pagination-more-button.png — a diary with Entries per page set to 10 and more than ten entries in it, cropped so the last visible entry and the More button are both in frame.
The window only ever grows. There is no Less button, and nothing collapses again while you stay on the page. Reload the page and the Diary starts from the first page again.
The More button only appears while there is something left to reveal. If your diary holds fewer entries than the page size, you will never see it.
Which entries come first
Pagination follows the Order Of Entries parameter, so the first page holds the newest entries by default, or the oldest if you have switched the order around.
One consequence is worth knowing. With Oldest Entry First, a brand-new entry sorts to the very end of the diary — behind More. Diary still shows it to you straight away while it is being saved, because hiding an entry the instant you wrote it would look like the save had failed. Once the save completes, it takes its proper place at the end.
