Customize built-in models: professional mode lets you customize built-in models and adjust their configuration to your needs.
Expert mode without permission confirmations: in professional mode, you can manually enable the option to allow skipping permission confirmations, acknowledge the risks, and select expert mode to bypass tool permission prompts. Underlying safeguards, including blocked paths, remain in effect.

Install .fapp mini programs: double-click or drag in a .fapp package to start installation, with a dedicated file icon. Installation confirmation and permission to enable the mini program are handled separately.

Grouped branch sessions (experimental): branches can be grouped under their parent session for easier expansion and collapse. This is off by default and can be enabled manually in Settings.
