-@subheading ScholarLY
-
-ScholarLY is a library in
-@uref{https://github.com/openlilylib/snippets, openLilyLib} that
-provides functionality for annotating scores, making it possible
-to manage scholarly workflows completely in the context of the score
-document. So far it is possible to enter annotations of different
-types, produce clickable messages in the console output and export
-to text and LaTeX files.
-
-There are numerous feature requests to turn this library into an
-even more powerful and comprehensive tool, for example: Inserting
-music examples, producing footnotes, automatically applying styles
-to the annotated item (e.g. dash a slur, parenthesize an accidental),
-creating reports with point-and-click entries. For a full description
-of this project suggestion please visit
-@uref{https://github.com/openlilylib/scholarly/wiki/GSoC}.
+@subheading Improve internal chord structure
-@strong{Difficulty:} medium
-@strong{Requirements:} Scheme, possibly LaTeX, (optionally Python)
-@strong{Recommended:} Experience with or interest in scholarly
-edition and collaborative workflows.
-@strong{Potential Mentor:} Urs Liska
+The internal representation of LilyPond chords is not powerful enough
+to capture the nomenclature of jazz chords. Currently the chord has
+a root, a bass and an inversion. It would be nice to be able to handle
+stacked or polychords, minor/major, etc. In order to do this, an
+internal representation with the ability to capture the essence of
+complex chords must be developed. As a bonus, once the internal
+representation is developed, the output formatting of chord names can
+be improved.
+
+@strong{Difficulty:} Easy/medium
+@strong{Requirements:} Scheme (Guile), but the level necessary can be
+easily learned
+@strong{Recommended:} Chord theory and naming

+@subheading Adopt the SMuFL music font encoding standard
+
+For several years now a new standard for music fonts has been around:
+@uref{http://www.smufl.org/, SMuFL}, which is also discussed as becoming part of
+a future W3C standard for music encoding. As a FLOSS tool LilyPond should
+adhere to such an open standard instead of using an isolated solution like it
+does today. Adopting SMuFL will help integrating LilyPond with the world of
+music notation software and eventually give LilyPond users access to a wider
+selection of notation fonts.
+
+Making LilyPond compliant to SMuFL includes remapping of the glyphs that are
+built from METAFONT sources, adjusting the glyphs' metrics to SMuFL's
+specifications, and finally updating the way LilyPond looks up and positions the
+glyphs. As an optional part of this project LilyPond's font loading mechanism
+could be modified to use notation fonts installed as system fonts instead of
+inside the LilyPond installation.
+
+@strong{Difficulty:} Easy/medium
+@strong{Requirements:} C++ and willingness to get familiar with LilyPond
+internals.
+@strong{Recommended:} Interest and experience in working with font files.
+A little bit of METAFONT.
