[NTG-context] footnotes (short: behind, long: below)?

Hi, is there a predefined command for placing short footnotes at the bottom of each page but horizontally continuos? Is saw this way of typesetting footnotes in an "old" (seventies)-typeset philosophical book. It looks likes this: body text body text body text body text body bo- dy text body text body. ------ 1 short 2 short 3 too 4 short 5 but hey: the long note starts in a new line! I have never seen footnotes like this before. But it reads very pleasant: This way you don't have lot of empty white space (withs short notes), and it still is very clear (for the long footnote starts on a new line). Is it possible to typeset this in ConTeXt? Steffen
