* 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.
