Hope you enjoy it! 
Currently editor integration is generally basic. Load file, eval line, eval top form etc works in most editors, it’s possible to get jump to definition and auto completion going pretty easily. Using arcadia there is also a pretty cool breakpoint system which is detailed in the arcadia wiki.
I’m actually working a bit on emacs/vscode integration. Miracle that I use is a fork of monroe-mode that I maintain, which enables go to definition and auto completion. For debugging I generally use the breakpoints and miracle.save.
If you have any wishes for support in vscode/emacs, please tell me, because those are the environments I’m working on. If you are more interested in other editors, check out the wiki and come talk to us at gitter!
