The Zedd project appears to be dead. There has been no activity on the code for a while. I'm not running a ChromeOS/Cloudready on my machine any more - so I don't have a use for a ChromeOS based editor. I do run ICEcoder ... if I need access from a remote client.
Shame, it was quite good, but there you go.
Zed is a Chrome app code editor - which means it runs on any platform Chrome Browser runs on. Including Chrome OS!
Zed also has a serverside application that allows the editor to edit files remotely.
This makes it a pretty good editor for Chromebooks.
