I have added a suggestion to add the ability to collapse the highlighter palettes when using the visual filter tool (so it would work the way they do when applying highlights). Currently all the palettes are opened in a long list with no way to collapse them. Especially since there is no way to place user palettes above the built-in palettes in the list, it causes an inordinate amount of scrolling to access a desired palette.
