I'm not sure if this is possible, but I've been playing around with adding a sidebar to the right of my passage through appending a div element, and it seems to work fine.
$(document.body).append('<div id="rightSidebar">/*Contents here*/</div>');
While I could probably just write HTML in there, I'd like to be able to add to it using passages just for ease of use. I'm still a massive novice at this stuff, so if it's impossible that's fine, just thought I'd ask. Thanks again everyone
where 'Test' is the name of the passage I'm using, seems to work fine. If there's a better way to do this let me know, otherwise I'll stick with this I'd love to get macros working too, dunno if that's possible though.
In the case of Sugarcane that order is alphabetical by passage title, other story formats may do it in the order the passages were created in the Twine application.
