Sesame, salt, and substance. A flagship bake.
Summary
Mouser is an open-source, lightweight software tool that serves as a fully local alternative to Logitech's Options+ software for remapping buttons on Logitech HID++ mice. It offers button remapping capabilities, per-application profiles, and works without telemetry, cloud services, or Logitech accounts. The software currently provides the best experience with MX Master family mice but includes early detection and fallback support for additional Logitech models.
