Categories are used to group tools by
type, and there is only one by default, "Uncategorized". For example, you might have a
category
called "Cordless Drills" and another called "Ladders". This helps with reporting and
filtering. Be as specific as you like, but keep in mind that each tool can only possess
Categories use the "Name" field, although have a prefix value as well. This is for the ToolId field on the tool. If a tool has an ID with an category prefix, it will automatically be assigned to that category. If the category is changed, but the prefix is not updated, it will revert to the category that matches the prefix.
