Keyboard Maestro can display a number of Palettes (or Toolbars).

Any macro with the Macro Palette trigger will be displayed in the Global Floating Palette. This palette appears whenever there is one or more active macros with this trigger, so it may appear and disappear depending on which macros are active (remember that Macro Groups control when a macro is active).

When you trigger more than one macro with the same action (such as multiple macros with the same hot key, device key, or typed string trigger), Keyboard Maestro will display the Conflict Palette listing the triggered macros and let you select the desired macro.

And finally, any macro group can be displayed as a palette.

You can control the appearance of the palettes in the Palettes preference pane or in the macro group configuration.

You can choose the style, the opacity of the palette, the size of the entries, the number of columns, whether the entries include the icon, the text and/or the trigger, and whether the palette shrinks when the mouse is not over it.
