Proposal

I would like some new features added to the application home page, which currently looks too shallow. If an application is to help me manage my files, it's should have this feature.
There should be details of the phone and SD card storage (size of the storages and space left on each). It should be placed on the Home page of the application.

Benefits

This would help users view their Phone and SD card Information. It is a feature any standard file manager show have at its home page.
It would help users decide which storage is free to receive file to and which is filled and need to be freed up.
It would also give users a better and beautiful home page, if implemented.
