Which Razer Synapse features do you find the most useful?

For me, the most useful Razer Synapse features are:

• Per-game profiles – having different DPI, keybinds, and lighting settings automatically switch when launching a game is incredibly convenient.
• Macros – not for gaming advantages, but for productivity tasks and repetitive actions.
• Hypershift – basically doubles the number of available buttons on supported devices.
• Cloud sync – makes it easy to restore settings after a Windows reinstall.
• Chroma integration – not essential, but some games use it quite well for notifications and effects.

Overall, I think profiles and Hypershift are the features I use daily, while Chroma is more of a nice bonus.

You can assign different actions to almost every mouse button, not just the standard left
