From now on it is possible to use If Statements within the chapter text. The syntax is described in the Chyoa Guide. Please let me know if something is unclear or if you have any questions about it.
This is a great addition. One question: I can only see and check if the paragraph is displayed correctly when I play the story, right? I just added a paragraph with a condition, and after publishing, it does not show up (because, obviously, I am not playing my story at the moment, so the conditions are not matched). I wonder if there is a way to display the words, sentences, paragraphs for authors. Similar to how chapter links are displayed for authors but not for readers.
If game mode is off, a condition can be marked as true (by adding @ behind if or elseif (if no @ is used, the else statement is supposed to be true)) Beyond that, it would be nice to have something like a "debug mode", where authors can browse their stories and define/change their variables directly (with update of the content).
