This knowledge is exploited many times over to make configuring even complex tags easy. Right-click tag editing is one example. Right-click on any tag to see a menu of the attributes for that tag. As you highlight each attribute, Agile tells you about it on the status bar.
Many attributes have submenus of values, such as the color menu shown in the picture.
Agile lists the values appropriate for the attribute, or provides helper dialogs to help you pick images, HTML files and so on. When you choose a value and close the menu or helper dialog, that's it. Agile edits the tag for you. At the same time it will automatically set the sizes for image tags, work out relative paths for URLs and so on. You can even configure the color menu to include your favorite shades.
