Tip #10 - Drag to Quickly Assign Categories
This is a short tip on one way to quickly assign categories to Projects, Tasks or other items, without typing or clicking around the Categories window.  It's an especially useful technique for easily assigning multiple, ad hoc categories that aren't in your Master Category List.
Step 1 ... Start with the Item in a Table View This technique is used when you have already created the "target" item.  Display the item in a table view, grouped by category (probably your default view).  In the example here, we are going to assign a category to [Bill's Newest and Greatest Project], that currently has no categories assigned.
