They are hosted right now as layers, which are overlapped on each other in the widget.
My coder apparently tells me that it is easy to do what you're asking, though. This is why I should ask before I assume! Hahaha. I'll let you know when the functionality is ready.
Edit: EZgames, I think your route was good. It's really hard to say, though. I already gave it my best effort, so my perspective on route is always going to be a bit biased. Haha. As for warps vs warpless, do whatever you feel comfortable with! The later warpless stages will be a *beast* to try to optimize, so it might be easier to start with warps?
As for warp info, there's a brief summary table here with CD threshhold:

You can also see each portal and the CD reqs on the map viewer as you load a map. Warps themselves are pretty simple; they're just like exit portals. You collect enough CDs to make them open, you jump into them to end the level, and they'll take you to some different stage.
Here's a link to my PB with warps, if you're interested in that route. I haven't listened to the commentary in awhile, but I imagine I talk about my justification for this warp route.
