[Feature] Folder size instead of global size

[Cwpute]

Describe your idea
It would be helpful to display the current folder's size at the bottom of the page, instead of the global available space and size taken on the current storage.

Describe why you want the idea incorprated
The global size is currently misleading in subfolders, as it's a device info that looks like it's dependant on the current folder vhich name is written just above.
Replacing it with the current's folder size would actually give it some usefulness.

[Optional] Additional information
Maybe this is actually a bug ? i don't know.
