Scheture is a hierarchical schematic capture system with built-in netlisters for Spice and Verilog. It has built-in plotting for Postscript, HP PCL and HP GL/2 printers and plotters. It includes a set of symbol primitives, and allows user-defined symbol primitives to allow for extensive customization of primitive properties. The system supports wire buses and iterated instances. The system also supports global pins and implicitly connected pins on a specific sheet. Supported platforms include Solaris and Linux (32- and 64-bit).
Notion is a tiling tabbed window manager for X. This means the screen can be freely divided into tiles that contain the client windows. Multiple client windows can occupy the same tile; in that case they will be tabbed, much like browser tabs. This way, windows will not overlap and it becomes easier to manage your screen real estate. Its functionality can be configured and even extended with Lua scripts. Various scripts are available, such as for NetWM features and multihead support.
