Adding Columns to the Resource Views
How can I add more columns to the Resource scheduling view?
In Admin Settings / Views you'll see an option for "Resource Columns to Show". Setting that will change everyone's default number of columns.
You can also change this on the fly from the drop-down menu on the resources tab:
Finally, you can also change the number of days that show up in this view--selecting up to 30 days at a time.
