Is your feature request related to a problem? Please describe.
Currently, to take a derivative (using LaTeX), you have to wrap your expression in parentheses and apply a prime (') which is cumbersome and limits you to taking a derivative with respect to the lexicographically smallest letter.

Describe the solution you'd like
Support Leibniz notation \frac{d}{dx} which more people in academics are used to and also allows for taking derivatives with respect to a specfic variable

Describe alternatives you've considered
For my application specifically, I've taken to replacing d/dx with ()'. However, this isn't a foolproof solution as you cannot select the variable to take the derivative with respect to
