Explore raw input handling for vendor-specific mouse buttons #4
Description
Summary
Investigate a lower-level input path for extra mouse buttons that do not appear through the current standard event flow.
Motivation
Some vendor-specific mouse buttons are not exposed through the current input stack, which limits automation coverage for certain devices.
Scope
- research Windows raw input options for extra mouse buttons
- compare raw input behavior with the current backend approach
- document technical tradeoffs and limitations
- if practical, add an experimental implementation behind the Windows backend
Acceptance Criteria
- the repository documents what was tested and what was learned
- the project has a clear next step for vendor-specific mouse input support
- any prototype remains stable for standard mouse input
