eowm (eet owter winvow manader) is a lightweight, dynamic tiling window manager for X11. While it started as a clone of catwm, version 2.0 introduces a unique column-based tiling engine designed for flexibility and efficiency.

Key Features

• Dynamic Column Layout: Organize windows into multiple columns.
• Multi-Monitor Support: Seamlessly handle multiple screens via XRandR.
• EWMH Compliance: Works with modern bars and docks (supports struts).
• High Performance: Uses a hash table for O(1) client lookups.

Layout: Dynamic Columns

Unlike the traditional Master/Stack layout, eowm treats the screen as a series of columns.

• Each workspace supports up to 16 columns.
• Windows within a column share height equally.
• Empty columns are automatically compacted to reclaim space.
• Fullscreen mode hides all other windows for total focus.
