When I use MacJournal 6, I notice black triangles next to some days (they may appear only for select days) in the calendar that appears at the bottom of the sidebar. What do these triangles mean?
In MacJournal 6, additional notations were added to the calendar, to help make it clear how many days on the calendar have more than one entry associated with them.
The calendar makes it possible to determine the days on which entries have been created. Let's say, for example, that you created entries on Monday, Wednesday, and Friday of last week; the calendar in MacJournal would color the corresponding days on the calendar in blue, to show that entries had been created on these days.
The calendar also provides functionalities that make it possible to navigate your journals chronologically. If you click and hold the mouse button down on a date in the calendar, MacJournal will display a contextual menu (a pulldown menu, like the menus that are accessed from the Menu Bar), with a list of all of the entries associated with the day you have clicked on. If you click on the Calendar and only one journal entry exists for that day, MacJournal will display the content of that entry in the editor pane.
If you click on a day in the calendar that more than one journal entry is associated with, MacJournal will only display the first entry. If more than one entry exists for a day, then, it might not be clear simply by looking at the calendar how many entries are available to navigate to for a particular day.
