[Roadmap] UX Improvements to incentivise token savings

[ffrappo]

Why The current UI both in mobile and desktop hides away the previous chats and it's not so immediate to create new chats. This leads to an increased incentive for the user to remain in the same thread. This goes at the cost of token spend and context exhaustion.

Concise description I propose the chat history is always visible on the left, with a "New conversation" button at the top, and "Start new chat" shortcut is placed near the message send area. On mobile, a button on the top right could do the job. As a reinforcement, a "system notice" every 10 messages in the chat area could educate the users about the benefit of starting a new chat, perhaps using the summarisation feature.
