The QGIS Numerical Vertex Edit plug-in used to work fine, but stopped working for me around about QGIS 2.6. I now use QGIS 2.8.1 Windows 64 bit.
The plug-in no longer seems able to see points or vertices on editable layers. Instead, it reports a Python code error: "AttributeError: 'NoneType' object has no attribute 'toBool'".
Uninstalling and re-installing the plug-in has no effect.
Is this just me being silly, or is it a problem others are finding too?
