codeintellify

Very cool. We (Sourcegraph) could never get VS Code fast enough to be the right fit for code browsing and search, which is what we're targeting. So we built our own components (open-source at https://github.com/sourcegraph/codeintellify). For browsing and search, you need fast loading, low resource consumption, a native system feel for text, etc. For editing in the browser, where you're likely to keep one tab open for a long time, it is an absolutely obvious choice. A huge undertaking for sure, and it's awesome that he was able to accomplish it!
