Hello,

From Designer, you can disabled default contributions in the Visual editor, or directly adapt the slot contribution from https://github.com/nuxeo/nuxeo-web-ui/blob/10.10/elements/nuxeo-web-ui-bundle.html

You can add easily your filters in your custom button (bottom section on the button definition)

For the default icons, you have to make your own slot contribution.

Regards
