New Window Add-on Request

Is it possible we could have something like this, where we can organize topics? Perhaps there might be a way to do this already, but wanted to share.
This screenshot below is from something I put together in ReactJS.

It's not clear to me from a screen shot like that what exactly you want that isn't already part of the user-editable book system. I might be able to guess (for instance, sub-topics?), but if you would, please write a couple of sentences describing the features you would like to see added.
