Customise the font and layout more

[danieljcroberts]

This builds upon request #1557. In addition to what is stated in 1557, it would be nice to be able to really customise the look and feel, including font, layout, width etc. as much as possible (more than the current options).

Here you can see how the Tavla setup looks on my dashboard. I have shrink it down, but if I had the option to hand pick the font size, I could make it in a way that maximises the space on the display:

Another options would be to get it in some plain HTML format that I could then adjust however I wanted outside of Tavla.
