Jennika - food rest? I could do with one of those to keep my nibbles on

I have a large desk with lots of space but it soon gets filled with 'things I must have to hand'. Chair and PC screen are all at a comfortable height.
The positioning of one thing I would like to alter if I could, which I can't, is the massive window behind me which is great for letting in natural daylight but when the sun shines, you have to lower the blind otherwise you cannot see the screen.
