When one has a number of custom highlighter palettes in support of visual filters and highlighting, apply a highlight in a visual filter becomes an onerous, obnoxious, annoying and inefficient task because the drop down shows all the highlight palettes expanded in alphabetic order - with the exception of putting the system supplied palettes first. This means I get to spend lots of time scrolling to the correct style.

My first choice of a solution would be for the drop down having a search box at the top for the palette name and for that name to be remembered until changed.
My second choice for a solution would be to leave the palettes closed - expand only when I select the palette.
What I don't like is playing games ... prefixing a palette with "AAA" so it will be the first after I scroll through the system junk so I can find it in a reasonable amount of time.
