I don't know if anyone feels the same, but I'm not happy with the spacing of commas in math mode (pictures attached). For instance, typesetting H^1(X,F), the comma seems to be closer to the F than to the X. Equal spacing on both sides or setting the comma closer to the X are I guess a matter of taste (inserting a \neghairspace after the X achieves the latter). In any case, I would kind of prefer equal spacing.

\setupmathematics[autopunctuation=no]

@Hans: I would suggest that this should be made the default.

IMO this does only partially help, consider the following example:

\starttext $(B, Y, R, X)$ \setupmathematics[autopunctuation=no] $(B, Y, R, X)$ \stoptext

In both lines the spacing after "Y" is way to big. I don't know if that's a bug or just ugly. (version 2011.02.15 16:11)

In text parts this is known as kerning. In OpenType math there are complex bounding boxes.

I would call it a bug. The spacing is OK with cambria, but not with xits.

But that is probably a "bug" in font, not in ConTeXt; and something that cannot really be handled in LM or in MKII at all. I already sent a similar report to Khaled (when I was testing XITS in Word), but he was somehow reluctant to change metrics (it has to be done carefully for the whole font, it needs a lot of time & work; might become obsolete with next release of stix; and just fixing two out of thousand such "bugs" doesn't really help).
