Adding Phone and SD card storage Information to Dir File Manager

Components

Dir is an Android application that helps in managing files stored on phone/SD storage.

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.

Mockups / Examples

I would use Es File Explorer file manager to illustrate this.
In the picture below I can see information of my phone and SD storage for my device.

In the picture below, we can see the boring home page of Dir File Manager with no information for my Phone and SD storage space.

Below I would show how I suggest this to be added to Dir File Manager.

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.
