     //  glyph size, spacing, line wrapping, etc.).  Buffers then use

+    - Buffer should only store the text itself and the encoding type.  The
+      undo stack and line ending type should be moved into the editor since
+      they only apply to editing operations.  The buffer should only store
+      data related to how the text is statically presented or stored on
+      disk.
     - Create BufferFormatters for console and for freetype, including
       preferences for tab width (specified in spaces) and line wrapping.
       The freetype formatter should not reference SDL at all, and should
       have only the freetype library itself as a dependency.
     //- Handle tab settings properly after the refactor
+    - Buffer needs a "reformat" method, which can be run after the formatter
+      is changed in some way (e.g. toggling line wrapping).
     - Possibly split the text buffer out into its own library...?  Would
       likely be useful to other people as well, and would encourage me to
       keep the API clean.
 
 - Custom line iterator code for file loading, because rust's built-in one
   only recognizes LF and CRLF.
+- File loading is currently very slow.  Investigate.
 - Line number display
 - Line wrapping
 - File opening by entering path
