As I can see, you use two toolbars for two editors.
In this case, you should use each own sets of actions for each toolbar (i.e. a separate TActionList or TActionBar for each frame). Otherwise, actions on all toolbars would work with a single editor (RVAControlPanel.DefaultControl or a focused editor) at the given time.
Of course, ImageLists with glyphs can be common for all actions.
Next, how to link actions with a specific editor.
There are several ways:
1. Assign the proper RichViewEdit to Control property of all actions in the given TActionList or TActionBar. You can use a single RVAControlPanel in your application.
2. Use a separate RVAControlPanel on each frame. Assign it to ControlPanel property of all actions in the given TActionList or TActionBar.
Assign the proper RichViewEdit to DefaultControl property of each RVAControlPanel.
