Playground: Drop down picker obscures render window

[smprather]

Minor issue, but it would be nice if, while switching fonts to compare, the drop-down menu wouldn't obscure the render. OR, better yet, have two side-by-side windows to direct compare two fonts. I came to the playground to find which font was most readable at 6pt size. I have huge-wide static timing reports (almost 1000 chars) that are much easier to read w/o line wrapping. Thanks for this great tool!!
