Can I change the time increment from 15 minutes to something else?
Sure. Click on the Filters tab in the grey, left side of the calendar. If you're on a screen that shows time scales (like the Day, Week, Schedule or Grid screens) you'll see a setting for "time scale increment" toward the bottom of the screen. Simply change that from 15 min to another value. (Only the values shown in the pop-up list are supported. If you need another increment, get in touch with SeedCode and we'll put something together for you.)
You can also change the default behavior by editing the script "Load Settings - On Startup --- Edit Configuration Here ---". You'll see the default increment after the comment "Load default time scale" and the default increment for the Grid view after the comment "Load default time scale for Grid View (many people like "day" here)".
The Grid view defaults to a day scale (showing two weeks) but you can change this using the Time Scale Increment on the calendar's Filters tab: changing it to something like 1 hour or 15 minutes will bring it back to a single day's focus.
Can one calendar view have a different default time scale than the others?
Yes. Each of the calendar views is its own tab, and each tab has an object name.(Look here for more info on working with these tabs.) You can give one or more tabs their own default scale. For example, here is how you create a default scale for the grid view, whose tab object name is "Calendar Resource Scheduling - Horizontal":
How can I see more all-day events at the top of the screen?
Screens that show time scales (like the Day, Week, and Schedule screens) show all day events at the top of the screen in a separate section. The calendar shows 7 such events by default. If you'd like to see more you can drag the grey row separating the all day events from the timed events.
If you'd like to permanently change the number of all day events show, edit the script "Load Calendar Settings - On Startup" in the Settings and Sources section of scripts. You'll see a place to specify the number of rows right below the comment "How many rows should be used to show All-Day events on Day, Week, and Schedule screens?"
Note that you'll have to run the "Upon Opening" script to see your changes take effect.
