Is there any type of 3D IDE/Text Editor

I have been using a home grown preprocessor kind of program that replaces
placeholders with file contents and allows you to use constants so you
don't have to do something like:
border-width:3px;
//...
$myElem.css("left", (someWidth + 3) + "px");
Instead you just do
border-width: {@c:\\mywebpage\my-border-width.txt};
// ....
$myElem.css("left", {@c:\\mywebpage\my-border-width.txt} + "px");
This does a few things:
allows you to declare constants across html/js/css
allows you to break large files into smaller files
allows you to create html templates as html and easily reuse them in
multiple places or as a string in javascript
allows you to create html/css/js code as modules which can be dropped in
or taken out of different projects with ease.
Programming concepts are not always best represented as walls of text.
Sometimes it is easier to take a function out and display it next to other
code in the same file. Sometimes you want to see different parts of the
same file simultaneously (which a lot of text editors do allow).
Are there any text editors or programming styles which allow you to work
with your code in a more modularized or 3D manner? Maybe something like
this:

To the extreme end of this (and not necessarily what I am looking for
right now) would be an IDE that uses something like Minecraft to organize
code. That is, you would group all of your functions that perform a
particular type of function in this building over here. Or you would
arrange all of your classes in a field. For huge projects it might be
quicker to find these functions or classes and see the bigger picture if
things could be arranged this way. It might even reduce developer fatigue.
So like you would walk up to the module you want in the Minecraft IDE and
right click it and it would just open up the code in a text editor. ...the
code could by represented by a block in Minecraft.
