euclid-wm is a minimalist tiling window manager for X11. It is designed to
allow quick and easy management of numerous windows entirely from
easy-to-learn, Vim-like key-bindings. It seeks to do two things in particular:
balance the ease of use common among automatic-layout tiling window managers
with the flexibility of manual layout window managers, and create a useful way
to handle minimized applications.

Notion is a tiling, tabbed window manager for the X window system. "Notion" is often stylized as "not ion", with reference to a prior window manager named "Ion", which in turn is based on "PWM."

* Tiling: you divide the screen into non-overlapping 'tiles'. Every window occupies one tile, and is maximized to it
* Tabbing: a tile may contain multiple windows - they will be 'tabbed'
* Static: most tiled window managers are 'dynamic', meaning they automatically resize and move around tiles as windows appear and disappear. Notion, by contrast, does not automatically change the tiling. You're in control.

Features include:

* Workspaces: each workspace has its own tiling
* Multihead: the mod_xinerama plugin provides very nice dual-monitor support
* RandR: mod_xrandr picks up changes in the xrandr configuration without the need for restarting Notion (read this, though)
* Extensibility: Notion can be extended with lua scripts. Browse through the scripts collection
