I am working on it, but, as this extension is using basically entirety of GML syntax, it is a little more sensitive to breaking changes, so I have to readjust some things to workaround oddities.
For me, even if it won't support some of the new functionality (for example won't be possible to create sequences, structs or anonymous functions in "live" part of code, but will still work on non-live part), that's enough. I hope that at least this will be possible, and I'm keeping my fingers crossed for your success :)
