All rules can be easily grouped into the categories - a single category consists of chosen name and selected color. One category can belong to multiple rules at a time, and likewise, multiple rules may belong to one category. To manage categories you can use the Rule categories tab, located in the program's Settings.
The tab allows you to use Add, Edit and Remove buttons to change the categories configuration. When you edit a category that already belongs to some rules, the associations are automatically updated. Furthermore, when you remove a category that is present within some of your rules, all associations are automatically removed.
To add a new category, simply use the Add... button. You will encounter a small window named New category. Please provide the desired name of the new category and choose the appropriate color using the color picker. When you are done, simply click the OK button, so the new category will appear on the list. Similarly, you can use the Edit... button to update already existing category.
You can use same colors for different rules but name of a category must be always unique and be up to 50 characters long.
Number of categories assigned to one rule is not limited in any way. Two first categories are always displayed next to the rule name - rest of them show up on the General tab. Program displays up to 5 rows containing your categories. If there is not enough space to show all of them, the program will display information about that in the first row.
To manage all assigned categories, you can use the Assign categories button or right-click a rule and select Categories. To assign a category, simply select the checkbox located next to desired category name. What is more, you can manage the categories globally from here using the New, Edit and Delete buttons.
