I agree, they should focus more on quality, because there are still a ton of tiny, yet annoying issues.

In Webstorm it sometimes does not recognize comments (colorizes them as code), does not reliably recognize multi line ToDos, and frequently warns me in a if (myVar == null) that myVar may not have been initialized.

At least the last issue is as old as the hills, has been reported several times, and yet they seem to be unable to properly fix it.
