Thanks for the reviews. Sorry for not providing screenshots in the first place, screenshots and description of changes below.

 - Code font had been reduced to accomodate for code span highlights, this changes it back to original size (most noticable in method signatures)
 - Not enough distance between multiple items in "See Also" list due to removed code span highlight, now is back to using code font space.
