A “Filter” field at the top where you can enter or select a tag previously defined. Only the resources (Brushes, gradients, patterns, palettes, etc.) that have the specified tag, will be displayed.

You can enter several tags, separated with commas. In which case only the resources that have all these tags defined, will be shown.

Selecting a tag with the mouse works differently: only a single tag can be active at a time. If you want to select another tag, you first have to click the active tag to unselect that one, before selecting a different tag.

“Enter tag” field, below the list of resources can be used to add tags to the selected resource. The tags belonging to the current brush, gradient, pattern, palette, etc. are displayed.

You can add more tags to the current resource by clicking on one of the defined tags in the pop-up list of the field; or you can create your own tag for this item by typing its name in the field. The new tag will then appear in the tag list.
