Show HN: MemSignal - an experimental memory-pressure indicator for Windows

- MemSignal is a free, open-source tool (published on GitHub) that gives Windows users a live, graphical indicator of how much memory pressure their system is under — not just how much RAM is used, but whether the OS is actively struggling to keep data in memory. - Memory pressure matters because when Windows runs low on physical RAM, it starts paging data to the much slower SSD or hard drive, which can cause stuttering, lag, and freezes — especially in games, video editing, or running multiple VMs. - Typical Windows tools (Task Manager) show raw percentages (e.g., "80% memory used"), but don't clearly signal whether the system is in a healthy state or entering performance-killing swap thrashing. MemSignal aims to fill that gap with a simpler, at-a-glance indicator. - The project is "experimental" and early-stage; it was posted on Hacker News as a "Show HN" (a Show & Tell post where makers share their projects with the community).
