Inclusions are not inline, but you can make them inline by using "display:inline" (and if the enclosing card is Basic, editing it's HTML so that instead of having a p tag around the inclusion it has a div tag), so for example "Ethan McCutchen's favorite fruit isĀ {{Ethan McCutchen+favorite fruit|display:inline}}." will render as:
Ethan McCutchen's favorite fruit is .
When you're including a card that doesn't exist yet, you can specify what type it should be with something like {{Phoebe Owens+favorite fruit|type:Phrase}}. Try clicking on this and you'll see it in action:
You can put comments in Wagn cards by making an inclusion and beginning with a hash symbol (#). Use two to make a comment that's completely invisible to web browsers:
{{## completely invisible comment}}
And one to have it show up as an HTML comment (i.e. <!-- # only visible in HTML -->):
{{# only visible in HTML}}
