EMF provides great support for editing (CRUD) a model, but not for invoking EOperations. I propose a view that shows the EOperations of the currently selected EObject (in the active editor) and lets the user provide arguments before invoking the EOperation on these arguments.

I have implemented a prototype view, as follows:
- the view tracks the currently active editor and selection
- a combo box is continously populated with the EOperations of the selected EObject's EClass
- a property sheet below the combo box is configured to let the user edit the required arguments (using an dynamically created EClass and EObject) 
- the user may press an invoke button, to execute the EOperation within a ChangeCommand
- the result (or the Exception) is shown in a popup
