How about just reading official standards compliant documentation on the use of std::map and std::list? The latest version (edition 4) of The C++ Programming Language is due out in the middle of May so get that and see what the differences are between your code and the C++ standard. Plus it'll get you up to speed with more modern C++ usage and abilities that you are probably unaware of.

Visual Studio is perfectly capable of doing the "maximize real-estate for code" thing; in fact it's probably the best for that and I've never seen anything with comparable functionality when it comes to both hiding stuff when it's not needed and showing stuff when it is needed (both of which are important).  All the little pop-up dialogs and panels can be tucked away, they will come back when you mouse over them, auto-hide again when you mouse out, and automatically appear when you do something that requires them to be visible (so the "Output" panel can be hidden until you do a build, at which point it will automatically appear).

You should try Vim. Nothing comes close. You can have multiple windows open split exactly how you like them. Most of the time I have about 6 or 7 source files open at any one time and have a nice project display on the left. Plus it has auto code completion and automatic code checking via clang. I haven't found anything anywhere near as powerful on any platform.

You can also check out Jansson.

Jansson is great. Very easy to use and reasonably quick.

Very impressive graphics. Good job.

Something else that no one has mentioned yet is LLVM (Low Level Virtual Machine). It is designed to be a platform for exactly the kind of thing you are thinking of. It is used as a platform onto which higher level virtual machines can be implemented. I would highly recommend that you check it out as it is very cool. Plus it is licensed under a very liberal open source license so if you have commercial aspirations that shouldn't be a problem.
