Enhance Controls

[tracker1]

A couple suggestions on the navigation controls in modal mode especially...

If the display area is a landscape ratio and width / height is at least 1.25, then display the controls along the left side of the display. If the browser is touch capable (mobile or desktop), then use larger icons for the navigation controls... perhaps hidden behind a menu on the top-left, similar to the close button on the top right... Not sure if there is a common remote-control glyph that could be used for said menu (since the hamburger/dots glyphs may not be appropriate).

I just want to say this looks like a really nice control, and appreciate your effort... I also want to say I like how clean the UI is for it, moving away from the additions of lightbox style viewers.

Thank you for the suggestions.
