Idea (Feature Request): Allow Smart Groups to become palettes? That way, you are effectively creating a palette based on a search criteria, similar to the function of tagging.
Wow, As I think about it, one very practical scenario is to create a Smart Group based on how recently a macro has been used (or how many times). If that Smart Group were a palette, you quickly show a palette of all your most frequently used macros, which you could trigger with their hotkeys, or drill down with keystrokes as through a conflict palette.
