  * Save and Load from Prompts: You can now save and load configurations directly from prompts.
  * Save and Load from Default Model Config: Default model configurations can be saved and loaded.
  * Budget Token Management: Added the ability to adjust the budget token value.
  * Thinking Configuration Toggle: You can now enable or disable the "thinking" feature.

  **Important Note:** The default model config does not automatically apply to saved prompts. To include default thinking settings, ensure they are saved within the specific prompt.
