The ability to see how the space is used on your device would be great. Think "Unclouded" or "Disk Usage" but built in would be fantastic

Please implement this, there is open source code available for this, it's a very old Linux feature. X-plore has a nice implementation even in their free version.
EVERYBODY has the problem of no space left on sdcard from time to time, this feature brings great advantage and productivity gain.
