This is my sandbox.


 * $$\begin{align}

\mathbf{E} &= -\nabla V - \frac{\partial \mathbf{A}}{\partial t}\\ \mathbf{B} &= \nabla \times \mathbf{A}\\ {D_\mu }L &= \frac{D_\mu }{\phi } + \frac{D_\mu }\left( \right) + \frac{D_\mu }{g^{\lambda \nu }} \end{align} $$

The general gauge transformations now become not just $$V \rightarrow V+C$$ but
 * $$\begin{align}

\mathbf{A} &\rightarrow \mathbf{A} + \nabla f\\ V &\rightarrow V - \frac{\partial f}{\partial t} \end{align}$$
