+\startchapter[title=Introduction]
+
+You can do a lot in \CONTEXT\ but for sure there are limitations too. There are
+quite some sub|-|mechanisms and sometimes there are more solutions for one
+problem. For instance, we have several table mechanisms and several
+multi|-|column mechanisms. In this document we will collect information about
+what doesn't work (well) and if possible indicate why. Feel free to submit more
+items. We will also discuss features that do work in most cases but are somewhat
+unreliable.
+
+Does that mean that we cannot make everything work? No, sometimes demands are too
+conflicting. Yes, we can implement more, but it simply doesn't pay off to spend
+time on writing code that is used seldom. Keep in mind that much of \CONTEXT\ is
+written in spare time without any compensation. Publishers have demands but
+seldom are willing to pay for it. Users have demands and no means to pay for it.
+On the other hand, user demands often have challenging properties that trigger
+development. Sometimes a project has as side effect that some mechanism become
+better.
+
+The good news that one can often work around it. Not all typesetting has to be
+fully automatic. And there are always reasonable typographic alternatives. The
+examples shown here can be run on your machine.

+
+\startchapter[title=Columns and notes]
+
+Because \TEX\ doesn't really support columns we need to cook up some magic to
+achieve them. Especially a mix between single and multi|-|columns is sort of
+tricky. Because notes are inserts and inserts play a role in determining the
+optimal breakpoints they can interfere badly, depending on the mechanism used. In
+\CONTEXT\ we use mixed columns for multi|-|column itemizations and as these can
+have footnotes you can end up in troubles.
+
+\typefile{notnow-columns-and-notes.tex}
+
+In such case the notes are postponed and flushed {\em after} the itemized list so
+they can end up on a next page. If this happens depends on how much room there is
+on the page. Solutions are possible (and the old \MKII\ column handler might
+behave better in some cases) but it's not worth the trouble to complicate the
+already complex code more than needed. Also, it will never be perfect anyway.

+\startchapter[title=Sidefloats]
+
+Support for side floats is non|-|trivial and no solution will serve all intended
+usage. Over the years we have improved on border cases but it is still not
+perfect. For that reason the implementation is (apart from solving bugs, mostly) frozen.
+Here is an example of a use case that we ran into. We manipulate the spacing with
+an offset parameter.
+
+\typefile{notnow-sidefloats.tex}
+
+You can best play with these parameters and see what they do. If you use this
+mechanism in a long term project, use a frozen instance of \CONTEXT !
+

+The second pages has preceding and trailing whitespace outside the sidefloat
+flow.
