Stefan Monnier - the Emacs maintainer - has already indicated two projects. Both concern overlays. A very dedicated and an ambitious contributor can, by pushing the limits, can even get intimate with the display engine - apparently one of the holy grails. 1. Using interval trees for overlays Programming language: C http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00308.html 2. Introduction of "text planes". Programming language: Mostly Emacs Lisp, may involve some C http://lists.gnu.org/archive/html/emacs-devel/2010-10/msg00177.html For the most ambitious of the students, 3. Improving the performance of the display engine particularly for a typical Orgmode workload. Focus on Eli's followups in this thread. http://lists.gnu.org/archive/html/emacs-orgmode/2013-04/msg00696.html. There may be some requirements on concurrent Emacs side. I have never seen a self-contained, well-defined work item myself. Jambunathan K.
