Add Media Files Button to Sidebar

[PaulJ00]

I suggest adding an additional button to the left sidebar that allows users quick access to Media Files. For users with limited browsing skills (like older people), it can be difficult to locate images through the current list bar.

Ideally, administrators could choose whether or not this extra button is visible to users. I would also prefer if the images were displayed as small thumbnails instead of just a text list without graphics.

If this idea is accepted, I’d be happy to implement it myself and submit a pull request to the main repository.
