[Enhancement]: Add Pins, Notes, and Variables (or Slots) to conversations, and provide the ability to extract them

[distardao]

What features would you like to see added?

I have three ideas to enhance the chat experience:

• Assign numbers to each message in a conversation to make it easier for users to locate specific messages and measure the overall length of the chat. Important messages can be pinned with additional text at the top of the chat, similar to how messaging platforms support quick navigation.

• Add notes to chats (with optional titles) to improve the user experience — especially when users need to jot down information for later use.

• Implement variables or slots (slot-filling method) to quickly collect data from the conversation — either automatically by the LLM or manually by the user.

Notes, variables, and slots could help provide a more detailed context for LLMs and agents to focus on. Users could use these tools to enhance the prompt context, or feed structured data into new workflows, MCP, agents, etc.

For example:

• User can send a prompt like: "extract this result into @slot#1" to push data to a variable or slot
• User can send a prompt like: "use @note#1, @slot#1, @slot#2 to create a...."
