Hi Peter.

Right now you can only add an action to the context menu by adding to the  class side of GTPlayground  a method annotated with <playgroundContextMenu> that takes a parameter and returns a list of glamour actions. The parameter will be the actual instance of the playground. You can find an example in #contextMenuBasicActionsFor:

GTPlayground class>>#customActions: aPlayground

<playgroundContextMenu>

^ {

GLMGenericAction new

action: [ self inform: 'action' ];

icon: GLMUIThemeExtraIcons glamorousBrowse;

title: 'Action' }
