The better way to interact with the code

It would be cool to use a more convenient code editor when working with functions and expressions. Implementing an editor, for example, based on https://ace.c9.io/ + https://github.com/breejs/bree (for sanboxing) could solve the problem.

Hi @maxbaluev!

Thanks for these resources. We are hoping to work on refactoring the expression editor this quarter and so will take a look at these resources during the research phase.
