Editor using editable Div container is really better, for various reasons, that editor using iframe.
Inline Editor can be the solution, but I want also a nice standard editor as the standard mode.
A simple and good solution can be add a new parameter as "toolbarContainer" that is a dom element where editor put the toolbar.
If noset in standard mode, editor apply standard strategy and put it in a div on top of iframe.
If noset in inline mode, editor apply standard strategy and put it in a flying popup.
if set, toolbar editor put toolbar in the selected area.
