Separate layer-options sidenote from the main text (#211)
Separate layer-options sidenote from the main text (#211)

Before this change, the text about loading options was slightly confusing.
This was because it was conflated two topics that are related but are relevant
in separate contexts. By separating the other topic as a side note, the text is,
hopefully, clearer for newcomers.
