v6.0 adds a search bar for your Nova Settings so that you can find a specific setting or toggle much faster than before. On a related note, your home screen search bar can now be configured to search Google or Nova Settings.
Nova’s also added a ton of new customization tools for your folders. Users can now configure folders to open in a windowed or immersive mode, match their shape to the adaptive icon style that’s being used, and add vertical or horizontal scrolling to them.
Other goodies include more shapes for adaptive icons — including custom adaptive shapes — no longer needing Nova Prime to resize icons, and an option to automatically match the folder and app drawer icon size to the one being used on your desktop / home screen.
The update should be rolling out right now to stable users. Beta users that have been using this for months: which features are you enjoying the most?
Updated March 2019: The update is pushing out to the stable channel.
