The footnote references and cross-reference references (!) look too similar. I wonder if they could not be more clearly distinguished in the text, e.g. by using a different typeface or weight or style (e.g. letters/numbers) on the footnote references (since they are fewer in number). e.g. check out Ac 14:23 where there are two references and they look very similar.
When reading through I may want to hover over footnotes but ignore cross-references, and at other times I may be more interested in cross-references ...
So this is a plea to have it changed so I am able to spot the difference more easily ...
