 ## Objectives
 
-In retrospective, _User Experience_ seems to fit the ambiance of the sprint
-(**badly said**), and is generally a theme that comes back regularly within
-the community lately.
+We started the sprint with a short standup, to discuss ideas gathered during
+the previous weeks online, and to narrow the focus to a few feasible items.
+At this point it became clear that User Experience (UX) would be an important
+topic during the weekend, as it is also within the XMPP community of late.
 
-At the beginning of the sprint, here is roughly what we planned to work on:
+Here is roughly what was mentioned, and what we planned to work on:
 
 1. Bookmarks: Sync [Private XML](https://xmpp.org/extensions/xep-0049.html)
    bookmarks with [PEP](https://xmpp.org/extensions/xep-0048.html) ones.  
    XMPP has different standard places to store bookmarks, and this has often
    proven to be a painful experience to the user, when using different clients
    for examle.  The objective here was to transparently synchronize both
-     stores, so that the user gets an overall nicer experience.
-2. [Message Attaching](https://xmpp.org/extensions/xep-0367.html)  
-   **TDB**
+   stores, so that the user gets an overall nicer experience.
+2. [Message Attaching](https://xmpp.org/extensions/xep-0367.html) and
+   Reactions.  
+   Message Attaching defines a way by which one can indicate that a message is
+   semantically related "attached" to an earlier message in the discussion.
+   This can be useful for reactions, for example, or even for previews of
+   links.
 3. [In-Band Registration](https://xmpp.org/extensions/xep-0077.html) in
    clients that don't support it, namely dino and poezio.  
    In-Band Registration is a mechanism that allows clients to provide an
    interface to create accounts on servers that allow it.  This way the user
    doesn't have to go through multiple hops to start chatting with their
    friends.
-4. Reactions  
-   **TBD**
-5. [Consistent color generation](https://xmpp.org/extensions/xep-0392.html)  
+5. [Consistent color generation](https://xmpp.org/extensions/xep-0392.html).  
    This specification aims at providing algorithms that will be used to
    generate deterministic colors, so that they stay consistent across clients,
    and thus help with recognition, for nicknames in groupchats, for example.
-5. [Hats](https://xmpp.org/extensions/xep-0317.html)  
-   Hats are **TBD**
+5. [Hats](https://xmpp.org/extensions/xep-0317.html).  
+   Hats allow for customised roles and affiliations in chatrooms, an extension
+   of the usual roles and affiliations. They can be used a regular "titles"
+   that are displayed to other users, (e.g., "Teacher", "Student", "Developer
+   of XYZ"), but can also carry permission information.
