saving projects from extensions

Mose librarites are good. The problem is ones like bignums and my hashtables library that add data types or replace primative blocks. These should be an extension.

I meant a fork of GitHub - jmoenig/Snap: a visual programming language inspired by Scratch, including both complete rewrites and also simpler things that add datatypes or edit primitives. Snap! Build Your Own Blocks 6.0.1 - dev - may not t, but most things do.

Another advantage of using forks is that you can have forks of forks, like json is a fork of hashtables is a fork of snap.
