While Windows 10's new File Explorer is just as, if not more, useful as it was in previous iterations of Windows, it could definitely still be better. Two features that would greatly improve File Explorer are tabbed results and a customizable user interface, similar to how they are in Google Chrome.
You don't have to wait for Microsoft to incorporate these features into File Explorer. You can get Chrome-style tabs right now, and even theme Explorer to be more like Chrome.
