Also needed: \xlongrightarrow and its relatives (\xlongleftarrow and so on)

Also, the package xymatrix would allow for drawing diagrams immediately, instead of first draw them in texmaker, then exporting pdf, transforming the pdf to svg using a command line tool, editing the svg to the right size using inkscape, uploading the file on commons and then embedding it.

@Mathmensch can you create one bug for each sepeerate request. That way we can keep the overview

@Physikerwelt sure gonna do that, but may take some time (need to go to supermarket now)

has been cancelled, can do it immediately

@Physikerwelt maybe I should create subtasks?

@Physikerwelt Is the current arrangement acceptable?

A summary of the requested features is availible from here: https://fr.sharelatex.com/project/595a8d960167d6487030b0d2

Is anyone working on this?

We first have to disable png rendering in production. Otherwise people using that mode won't be able to see the new symbols.

@Physikerwelt I want to be frank: I need the middle command. As soon as possible. The first WB is going out this week, and I want to do the print version for proof reading.

One more request is for an upright mu: μ. The use case is for units like micro-metre μm. Other upright Greek letters might also be useful.
