+This module improves the usability of translating **HTML** fields.
+
+The standard translation dialog of an HTML field splits its content into
+individual source terms (chunks) and asks the user to translate each one
+separately. This is technical and hard to use for end users, especially
+on rich content.
+
+With this module, the translation button next to an HTML field opens a
+dialog that shows one **full rich-text editor per installed language**.
+The user reads and edits the whole translation of each language as a
+single block, exactly as the field is edited in the form.
+
+The standard term-by-term dialog is kept untouched for ``char`` and
+``text`` translatable fields.
