two small typos and a suggestion

[SwitWu]

Since \postnotes isn't actually a command provided by this package, I changed the \cs{postnotes} into postnotes.

Hi @SwitWu , I'm glad you are having fun with the docs. :-)

Since \postnotes isn't actually a command provided by this package, I changed the \cs{postnotes} into postnotes.

True. But I think \cs{postnote}s would be slightly better here.

Also, while fixing the typos is of course much welcome, I think the "Implementation" section is a bit overkill for the User manual. Separating the implementation documentation from that aimed at regular users is a common practice. So much so that it is expected that advanced users are familiar with it, and also know where to find the code documentation if they want to. On the other hand, including a section for this purpose in the User manual hints regular users that the manual is not sufficient for them, which hopefully is not the case.

So, could you please review these two things before I merge?

And, thank you once again!

[SwitWu]

OK! I agree with your comments.
