It is essential that these features be fully supported to give a good experience.

I can't get syntax-rules to work in <http://feeley.github.io/gambit-in-the-browser/>: it says "ill-formed expression" to all macros. The same macros work fine in the command line gsi REPL on my computer.

The Gambit in the browser site is at Gambit v4.7.0 and hasn’t been updated in a long time.  That’s why I’m looking into rebuilding it with the latest Gambit and emscripten (and compressing the generated JS/wasm code).

I’m not sure I’ll have time, but it would be nice to add an in-browser code editor to create files (rather useful to try out writing libraries).  I may reuse parts of my codeBoot project which is a in-browser IDE for JavaScript and Python.
