I was thinking the layout of the editor could maybe be changed.
Instead of it going like this:
Perhaps it could be like this:
Just a thought, it would be pretty nice for people who have many pages in one chapter, they can get pretty confusing.
This probably could also be turned on/off in the profile.
If the pages get too cluttered, there could be dropdown menus or something like that to help.
I don't know much about the ins and outs of the site's code, but that sounds like it would be pretty difficult to implement. Don't get me wrong, it's a really cool idea and I'd love to see it added if possible, but I wouldn't get my hopes up. There are other programs out there that you can use to outline your story like this though. If you like doing things the old fashioned way, you can also just use pen and paper for an outline and go off of that when writing. Another idea, if you've got an old cork board and some twine lying around, you can use that too. Sure, it'll make you look like a crazy conspiricy theorist but on the plus side... it'll make you look like a crazy conspiracy theorist.
The point is, if you're having trouble visualizing the different storyline paths in your game, there are plenty of options out there that might help.
Hmm, you're right, I didn't think of that :P
