I would like to ask for a minor request: as the title says, can you make the variables and functions bold in the editor? For example the "z" in z:a+%i*b, or "f(x)" in f(x)=sin(x). It would be of a great help in fairly large chunks of input (%ixxx) text. Italic or underline would also stand out, but would be less visible. It's just a thought, if possible.
Anticipated thanks for either answer,
