+@chapheading Future Development of @previewlatex{}
+@end ifset
+
+@itemize @bullet
+
+@item Support other formats than just @LaTeX{}
+
+plain @TeX{} users and @ConTeXt{} users should not have to feel left
+out.  While @ConTeXt{} is not supported yet by released versions of
+@AUCTeX{}, at least supporting plain would help people, and be a start
+for @ConTeXt{} as well.  There are plain-based formats like MusiX@TeX{}
+that could benefit a lot from @previewlatex{}.  The main part of the
+difficulties here is to adapt @file{preview.dtx} to produce stuff not
+requiring @LaTeX{}.
+
+@item Support nested snippets
+
+Currently you can't have both a footnote (which gets displayed as just
+its footnote number) and math inside of a footnote rendered as an image:
+such nesting might be achieved by rerunning @previewlatex{} on the
+footnote contents when one opens the footnote for editing.
+
+@item Support other text properties than just images
+
+Macros like @samp{\textit} can be rendered as images, but the resulting
+humungous blob is not suitable for editing, in particular since the
+line filling from LaTeX does not coincide with that of Emacs.  It would
+be much more useful if text properties just switched the relevant font
+to italics rather than replacing the whole text with an image.  It
+would also make editing quite easier.  Then there are things like
+footnotes that are currently just replaced by their footnote number.
+While editing is not a concern here (the number is not in the original
+text, anyway), it would save a lot of conversion time if no images were
+generated, but Emacs just displayed a properly fontified version of the
+footnote number.  Also, this might make @previewlatex{} useful even on
+text terminals.
+
+@item Find a way to facilitate Source Specials
+
+Probably in connection with adding appropriate support to
+@code{dvipng}, it would be nice if clicking on an image from a larger
+piece of source code would place the cursor at the respective source
+code location.
+
+@item Make @file{preview.dtx} look reasonable in @AUCTeX{}
+
+It is a bit embarrassing that @file{preview.dtx} is written in a manner
+that will not give either good syntax highlighting or good indentation
+when employing @AUCTeX{}.
+
+@item Web page work
+
+Currently, @previewlatex{}'s web page is not structured at all.  Better
+navigation would be desirable, as well as separate News and Errata eye
+catchers.
+
+@item Manual improvements
+
+@itemize @minus
+@item Pepper the manual with screen shots and graphics
+
+This will be of interest for the @acronym{HTML} and @TeX{} renditions
+of the texinfo manual.  Since Texinfo now supports images as well, this
+could well be nice to have.
+
+@item Fix duplicates
+
+Various stuff appears several times.
+
+@end itemize
+
+@item Implement rendering pipelines for Emacs
+
+The current @previewlatex{} interface is fundamentally flawed, not only
+because of a broken implementation.  A general batchable and
+daemonizable rendering infrastructure that can work on all kinds of
+preview images for embedding into buffers is warranted.  The current
+implementation has a rather adhoc flavor and is not easily extended.
+It will not work outside of @AUCTeX{}, either.
+
+@item Integrate into Ref@TeX{}
+
+When referencing to equations and the like, the preview-images of the
+source rather than plain text should be displayed.  If the preview in
+question covers labels, those should appear in the bubble help and/or a
+context menu.  Apropos:
+
+@item Implement @LaTeX{} error indicators
+
+Previews on erroneous @LaTeX{} passages might gain a red border or similar.
+
+@item Pop up relevant online documentation for frequent errors
+
+A lot of errors are of the ``badly configured'' variety.  Perhaps the
+relevant info pages should be delivered in addition to the error
+message.
+
+@item Implement a table editing mode where every table cell gets output
+as a separate preview.  Alternatively, output the complete table
+metrics in a way that lets people click on individual cells for editing
+purposes.
+
+@item Benchmark and kill Emacs inefficiencies
+
+Both the @LaTeX{} run under Emacs control as well as actual image
+insertion in Emacs could be faster.  CVS Emacs has improved in that
+respect, but it still is slower than desirable.
+
+@item Improve image support under Emacs
+
+The general image and color handling in Emacs is inefficient and partly
+defective.  This is still the case in CVS.  One option would be to
+replace the whole color and image handling with @acronym{GDK} routines
+when this library is available, since it has been optimized for it.
