Runs well, but there is room for improvement – Continuous .NET C# and F# IDE Review

Is this app still being supported? There seems to be a new bug since the iOS 11 release. (It was present under iOS 11 beta also) When pasting in code that is not at the end-of-file the app crashes. Some of the other iOS 11 features (Drag-n-Drop text) would be nice to have also.
