comment Using TraditionalForm to express equations
@QuantumDot: to a first approximation, your formulation matches what I have in mind. The main difference is that, I don't see why this two-column formatting couldn't be limited to a few cells (rather than extending over the whole notebook).

comment “LinkOpen::linke : specified file is not a mathlink executable”
@mitochondrial: I just had a random (and, admittedly, very farfetched) thought: MATLAB files also end in *.m, and therefore in some systems, MATLAB is set as the default program for such files. Could there be a weird interaction between Mathematica and the desktop environment that leads Mathematica to conclude that a particular *.m file is not a "MathLink executable"? Grasping at straws here... I'd test this idea myself, but I no longer have access to the system where I got this error.

@mitochondrial: no, I never did, unfortunately.

comment Trouble exporting graphics to SVG (or PNG)
@YvesKlett: for PDF I've gotten better results, but the image looks different depending on the software I use to view it. For all viewers I've tried, the image doesn't look quite right, although the latter seems due mostly to pixel alignment issues, so it may be a problem with the original image rather than the method of export.

@C.E.: I added a synthetic example. Unfortunately, it does not faithfully reproduce all the problems I've run into, but it's the best I have so far.

@C.E.: Not readily. The code used to generate the configurations is pretty big. I'll try to come up with a suitable facsimile.

comment Is there a global setting for Mathematica's base fonts?
@ShutaoTANG: thank you, but none of the answers in the thread you linked look global to me. As mentioned in my post, I know that one can customize individual cell styles, and individual notebooks. I'm looking for a global customization, one that should uniformly affect every notebook and every style.

comment Looking for an extensive gallery of Mathematica's 2D graphics
@MikeHoneychurch: fine: it's the Matlab-inspired Matplotlib library for Python. This library is considered the "standard" graphics library for Python, and the Python world is generally mighty impressed by it, which means that there's little hope for anything better. Matplotlib started out as a side-project hack (by its author's own description), and it "grew" into the Python standard. IMO, the design of something as important as a language's representation of graphics needs more careful thought than what went into Matplotlib.

comment How to scale one axis of a 3D plot?
... parametrized with {Sin[u] + Cos[v], Cos[u], Sin[v]}, because with this new function the proportions of the underlying 3D graphics are different.

comment How to scale one axis of a 3D plot?
Thanks, but no, this is not what I am looking for. The desired solution should be invariant with respect to changes in the proportions of the underlying 3D graphics. In contrast, the solution you propose requires inspecting the proportions of the underlying base graphics, and using this information to compute the required BoxRatios to produce the desired scaling. IOW, the code above would fail to properly scale the y-axis if, for example, the function being plotted were...

comment EdgeForm with Graphics
Try adding the option Frame->True to your Graphics expression. You can turn off the tick marks with the additional option FrameTicks->None. You can use the options PlotRange and/or PlotRangePadding to control the spacing between the frame and the contents. BTW, EdgeForm is unrelated to what you're trying to achieve here.

comment How to get arrowheads scaled to be a fixed fraction of the arrows' lengths?
Thanks! After I tried your answer (and also Nasser's), I realized that the wording of my question was ambiguous. I have added a couple of sentences to my post to disambiguate it. Basically, the arrowheads need to be a fixed fraction of the length of the arrow. (If you multiply all the points in pts by, say, 0.01, you'll see the problem.)

comment How to implement a live-searchable table view?
@Kuba: agreed. Inexplicable gaps like this one is one of the reasons that Mathematica gets its clocked cleaned (market-share-wise) by overall vastly inferior rivals (e.g. MATLAB). I wonder if the reason for such gaps is that filling them entails implementing familiar, run-of-the-mill stuff, with little room for mind-blowing, epochal innovation; they just can't work up the enthusiasm for the job. (Ironically, it's precisely the humdrum, everyday, thoroughly familiar stuff that people often miss in Mathematica... Like simple options for specifying ticks, for crying out loud...)

@chuy: Sorry, I don't think you understand my point, but I don't know how to explain it any better than I have. I can only hope others can see what I mean.
