Unity Game Engine
I know this one would be kind of hard, but I would just LOVE being able to code with the Unity Game Engine with languages such as C#! Please give it a thought!

Java 11 support
As Java 11 is Oracle's long term support (LTS) option for SEs and public updates of Java 8 are no more (+) - having an option for Java 11 with repl.it has become a requirement for most of my teaching (we've moved from 8 to 11 based on the local employer feedback here). I understand the licensing difficulty with Oracle and SEs (all to well) but at least the option for the OpenJDK11 would allow for 99% of the features.
