I know there are some softwares out there that do some dependency scraping, and will help you navigate around your code-base, I just envision one that does more in certain areas, and feels better in others. Making an editor that feels like google maps in some places, a spider web in others, mind-maps in others, and vim in the code parts. It would be smart enough to let you move methods from one class to another class, and automatically update instances. It also needs to allow you to 'highlight' parts of the code base, because I have an editor engine, and a frontend/exported engine ( the animation software exports to html5 and the html5 export version is slim, whereas the editor version has a lot of extras for editing ), so that's one of the big areas, I don't want to maintain 2 code engines anymore. So, a big part of it would be toggling certain lines of code to target to different versions, and then being able to toggle views as well.
This might be too big of a side-track at the end of a project, and I could be just wanting something else to work on, because mature projects get very un-fun. It is something I probably will do eventually, to help myself manage the two similar engines.
The other option is doing some sort of a JS lint type thing, where I just comment out the extras and they only get compiled in the editor version.
I wish someone would just give me $50k for 5%, and I'd have another year to get things ready for mass markets. When I launch I think the animation software will grow nicely, so I want my ducks in a row so I'm not too stressed. That pressure is counter-acted by the fact that I could use cash to live on, cuz 2 years of development with just a little free-lance is kinda draining.
