Problem Statement

aWhen having long conversations with multiple open questions/topics, it is impossible to track which response belongs to which question. There is no way to reply to a specific message or maintain threaded conversations. This leads to lost context and confusion, especially when the AI asks multiple questions or when discussing several parallel topics.

Currently:

• No reply button on individual messages
• - No threading or topic separation
• - - Multiple open questions get tangled together
• - - - No way to reference a previous message in a reply

Proposed Solution

aAdd a session/topic panel with numbered glowing tiles (1, 2, 3) next to the chat:

1. Each active conversation topic or open question gets its own numbered tile
2. 2. Active tiles glow/pulse so the user always sees what's pending
3. 3. Clicking a tile continues that thread (like clicking 'continue' on a specific topic)
4. 4. Reply button on each chat bubble — clicking it quotes that message and links it to a thread number
5. 5. Max 3 active threads visible at once to avoid overwhelm

This would make multi-topic conversations with AI agents dramatically more manageable.
