Added

• Scroll down button
• If hide_cot is set to true, a running loader is displayed by default under the last message when a task is running.

Changed

• Avatars are now always displayed
• Chat history sidebar has been revamped
• Stop task button has been moved to the input bar

Fixed

• If hide_cot is set to true, the UI will never get the intermediary steps (but they will still be persisted)
