Squire vs CKEditor

The Squire implementation is not 100% compatible yet, but it shows the massive overhead of CKEditor.

Still TODO:

  • support for tables (really needed?!?)
  • support BIDI (really needed?!?)
normal min gzip min gzip
squire 122.321 41.906 31.867 14.330
ckeditor ? 520.035 ? 155.916

CKEditor including the 7 asset requests (css,language,plugins,icons) is 633.46 KB / 180.47 KB (gzip).

To use the old CKEditor, you must install the plugin.
