Does DynamicExpresso has any expression editor?

[evolcano]

DynamicExpresso is good enough to parse and evaluate expressions. I need a visual expression editor to enable the user to create User-define expressions.

1、Does someone already add a expression editor to DynamicExpresso ? 2、or recommend some relevant repository to reference if someone want to implement it?

As I know there isn't any ready to use editor. In the past I have used https://codemirror.net/, that can be customized for such use cases.
