PWM is a lightweight window manager for the X Window System, known as one of the first programs to introduce managing multiple windows grouped as tabs within a single frame. Ion is the follow-up project in which the same developer combined this idea with tiling, and it influenced the tab group concept in today's tiling window managers. Its development has stopped, so it is now closer to a historical reference.
