Configure Razer Naga Hex V2 (without running Synapse)

Features

• Designed for Windows (unlike most other projects)
• Configure mouse without having to use Razer Synapse
• Settings stay changed after program is terminated

Notes

• Button remapping is not supported. The program would have to keep actively monitoring key presses to be able to support that.
• Nothing is shown when the program runs. This is so that the program can seamlessly run on startup, ensuring the mouse settings are always correct.
