This sounds like it's relevant to https://github.com/leo-editor/leo-editor/issues/465 although actually that issue has less relevant discussion than I thought. Briefly, for the leo-edit-pane (LEP)project https://github.com/leo-editor/leo-editor/issues/778 I added a simplistic signal manager https://github.com/leo-editor/leo-editor/blob/master/leo/core/signal_manager.py which is currently emitting a signal used by LEP https://github.com/leo-editor/leo-editor/blob/master/leo/core/leoNodes.py#L2550 from vnodes on body text changes. Although I'm wondering if more of this approach is used it would be better to switch to https://pypi.python.org/pypi/blinker I vote against Qt signals because I could see this architecture wanting to work in non-Qt contexts.
