Thanks, Aditya. However, I'm don't think that \setupfloat[figure][default=here,top,bottom,page] addresses my need for float pages. If you compile the document below, you'll notice that the figures at the end of the first section are floated throughout sections 2-4. I would like the rendering of the floats to catch up by placing the floats on float pages, before moving on to other text. Is this possible in ConTeXt?
