That brings to mind an interesting idea for an IDE: having one big virtual file that you edit, which gets split into multiple physical files on disk

If you're going to work with it as one big file, then what's the point of multiple physical files anyway? Just store it as one big file then.

Why store it as a (text) file at all? Why not store the code in a database? Or as binary? Then you can store metadata pertaining to the code and not just the code itself. Unreal blueprints are an interesting way of structuring code and providing a componetized api. It would be interesting if they were more closely integrated with the code itself. Then you could manipulate data flows, code and even do debugging from inside the same interface.

Yes, this is all pie in the sky stuff, but it's interesting to think about.

I have been toying with the idea to store programming projects in a single sqlite3 database butt never seen enough value to actually pursue it.

As you mentioned though, it's interesting to think about.
