The Favorite Plugins window is on the top-left side of the Mixer Window. Like other elements in that window it has variable height and can be hidden by dragging it to zero-height. If it is not visible, the top-handle can be grabbed and dragged down to reveal it.
Plugin names that have a right facing triangle next to them have presets associated with them; clicking on the triangle will cause all presets associated with the plugin to show in the list.
Features
The Favorite Plugins window provides easy access to frequently used plugins:
Plugins can be dragged from the window to any track or bus processor box, which will add the plugin to that track or bus at the given position.
The list includes user-presets for the plugins. Dragging a preset to a given track or bus will load that preset after adding the plugin.
Double-clicking on a plugin or preset adds the given plugin to all selected tracks/busses pre-fader. Other insert positions are available from the context menu (right click).
Dragging a plugin from a track into the window will add it to the list and optionally create a new preset from the current settings. The horizontal line in the list shows the spot where the plugin will land.
The context-menu allows the deletion of presets or removal of the plugin from the list.
Plugins in the list can be re-ordered using drag & drop. The custom order is saved.
When favorites are added with the Plugin Manager, they are appended to the bottom of the list.
