They fixed this, but relatively recently, and when they first announced they were killing the app, they did it without any promises about feature parity ETA (I think there are still more minor features missing in the extension). At launch the extension did not support a number of things that were in the app - this included fairly major features like secure notes and ID's.

They have more recently added Windows Hello to the extension, quietly - I actually didn't realize until just now that it is now int he extension. The desktop app was able to do things like use Windows Hello / biometrics for security - you were either logged into the extension or not, and when you are logged into the extension and the PC is unlocked, it is basically fully accessible.
