Collapsible Advanced Options & Remember Last Settings

[guansk]

1. Collapsible Advanced Options: Add a foldable section for advanced prompt settings.

Why: The prompt settings can significantly impact the quality of the generated content. A collapsible section would make it easier to fine-tune these settings without cluttering the UI.

2. Remember Last Settings: Save last-used settings (model, language) as defaults for the next time.

Why: When I need to queue multiple tasks, I have to open multiple windows and input the same settings repeatedly. This feature would save time and effort. Alternatively, adding a queue feature or a default settings option could also solve this issue.
