comment Where is the LaTeX manual?
@JosephWright May be a misconception from me, but I thought he didn't want us to compile it but no problem with searching its source (but as you say, it's probable that he expected us not even to search, per se, the source).

comment Where is the LaTeX manual?
@JosephWright Probably right, still… the fact that it's not free and nowhere accessible (the source, like The TeXBook), is not entirely clear in my mind.

comment Where is the LaTeX manual?
It always strucked me, why does LaTeX source (still) point to a non-accessible manual (at least for free, if I'm not mistaken)?

comment Standard for typesetting mathematical objects other than variables
I think the problem here is the fact that euler is not a typical font, it has its singularities (so the choice for text font in \log would be just because of euler font). In a more general sense: \sin is maths, e is maths, air is not maths. So, it's okey to have \log with \mathrm, it's acceptable (depending on the choice if you prefer upright math constants) to have \mathrm{e}, but air is not maths (altough I write it usually with \mathrm{air} may be \textnormal is the most correct way).

comment Typesetting for two variables muliplication
\newcommand*\cC{c\mspace{<whatever amount in mu>}C} That way you input it in a clear way, you can search & replace easily in your document, and you have control over the spacing in the whole document.

comment datenumber: define \dateshortmonthname
“This should be expandable, in my point of view.” I'm not sure what you mean by that, but that's not expandable.

comment Labeling equations and math mode
May be \renewcommand*\vec{\mathbf} and use \vec{q}.

comment Labeling equations and math mode
@user1930901 Rather than using \mathbf{q} I would think of what is that q. If it's a vector, the logic would be to input \vec{q} and then redefine \vec to give bold letters (by default it places an small arrow above the letter). In any case, you should change your name to something more telling than user1930901 :)

comment Creating a Blank space - Formula sheet
@Xaryu May be adding a “phantom”? like using \rule{0pt}{3cm} would add 3cm of vertical space.

comment Text formating depending on conditions
I don't see yet what exactly are you looking for. What's the problem with \bool_if:NT \l_sectioning_numbered_bool { <formatted number> }? If the problem is mixing various bools you have \bool_if:nTF. In my opinion you should be more concise and add details. Right now, I don't really understand the question.

comment Text formating depending on conditions
I think you have to give us more. What exactly are you looking for? Write an example, or explain a little more what you want to achieve. Remember you also have \bool_if:nTF.

With the KOMA-Script classes you just need \addtokomafont{pagenumber}{\bfseries}.

comment LaTeX3 iteration and token list comparisons-code improvement
Mmm… I'm not sure I understand (or you don't understand). If you want a function to be fully expandable, you need that everything inside is expandable and definetly \edef is an assignment, so it's not expandable.

comment LaTeX3 iteration and token list comparisons-code improvement
At first sight: Why are you using \cs_generate_variant:Nn inside a macro? Why all those _set and _gset? If you want an expandable function, you definitely have to leave those out. I'm not sure what you want to do, but you have \tl_item:nn at your disposition.

comment Subscript on $\rangle$
Well, all those lines are written inside of xparse for any argument type (like o, r, d, etc.). The fact that this is hand-made by me means that that code must come from “outside” of xparse. It wasn't really an answer to the question, but more of a “joke”; the only thing in those lines are the ability to write \inn{x,y}_{G} rather than \inn{x,y}[G] from egreg's answer.
