When a conversation is bookmarked in chat, it is added to two places:
- Conversation tab in the room info - example.
- Conversation tab in the user profile of the user who bookmarked it - example.
As you can see if you look at the examples, the conversations for the room are shown in two columns. For a user, there is only one column - with lot of empty space on the right. (On purpose, I chose as an example a user who has a lot of bookmarks, so it takes quite a lot of scrolling to get to the end. Changing the display in two columns would halve the amount of scrolling.)
Suggestion: Display the conversations in user profiles in two columns - similarly as for the chatrooms.
