The FilterHub panel remains open to display a configurable list of filters and plugins, and provides one- or two-click access to any filter. Useful enough, but it also allows users to go beyond the capabilities of the Filter menu, notably by being able to apply the last effect of any filter (not just the one last used) without displaying its dialog. Users can also paint or erase filter effects with the brush tool. It can run multiple filters from the favorites list with one click and renders the same filter effect on multiple layers in one or more passes. It can also apply multiple filters on multiple layers with one click.
