Hey pjmlp -- your comment inspired me to do some additional work. From the text console, you can run the ,brower command and it will open up your browser with a REPL on the same lisp image. The browser-based REPL has many interesting features .. too many to mention here. Please check it out again at https://github.com/atgreen/icl Thank you!

No, but now that I've looked, I'm hacking down another rabbit hole...
