When moving a Highlight style from one palette to another, there is a limitation in viewing all of my palettes in the "move to" drop down list. It seems to have a limited view of 27 palette names. I have about 43. Many of these coincide with visual filters.
My current work around is temporarily editing the name of the palette I want the style moved to by adding a(.) to the name to bring closer to the top of the list.
I don't believe this is anything new.
This is the same on Desktop 36.1.6 and 37.0 Beta 1
