Dear developers, First of all, thank you for a wonderful piece of software! I have been using LyX for almost two years now, while studying math & physics at the university, and I don't know what I would have done without it.
I have a request which I think would benefit many people. When writing certain mathematical expressions, such as definitions of sets: \left\{ \frac{x}{y}\middle|x\in A,y\in B\right\} or inner products in physics: \left\langle \varphi\middle|\frac{1}{2}\psi\right\rangle it is necessary to use \middle so that the middle vertical bar will be of appropriate size (the same as the brackets). Even though the code is supported by all LaTeX implementations, and is displayed correctly upon compiling, LyX does not know how to render it. Would it be possible to make LyX understand the \middle code and display the vertical bar correctly? Thank you, Barak
