The old extension created a summary on each turn with a green theme. This was a very useful feature that provided a quick overview of what happened on each agent turn.

Additionally this way you could easily see whether the agent was done or still working. It's now often not so clear, and having a feature like this will help. We need to consider whether we want the full summary though; there were also quite a lot of people who disliked this in the old extension because it cost extra tokens, and often duplicated the summary (once in normal text, once in green)
