能否增加一个代理地址输入的地方

我希望增加一个可以输入http://127.0.0.1:xxxx的地方，分别在安装程序和主程序里

Look for the installer and main application UI components where network or proxy settings might be configured. The feature requires adding an input field for a proxy address (like http://127.0.0.1:xxxx) in both interfaces. Check existing configuration files or state management to understand how settings are stored and applied. Testing involves verifying the proxy address is correctly captured and used by the application's network requests.
