Seiri

Seiri is a lightweight, event-driven tiling window manager for Microsoft Windows. It listens to native Win32 window events, computes a per-monitor tiled layout, and applies animated window transforms with minimal runtime overhead.

Build

There is currently no committed build system file (no CMake/project file in this repository). Compile directly from source.
