 * Lump manipulation in WADs and (STORE and DEFLATE only at the moment)
 * Ability to open archives-within-archives

 * PNG including the grAb and alPh chunks, and many other standard formats (BMP, JPG, etc.)

Older versions
SLADE 1.13 or 2.00-beta have the following features:
 * Support for Doom, Doom II, Heretic and Hexen
 * Uses SDL/OpenGL for fast drawing and cross-platform compatibility
 * DECORATE parser
 * Some general 'eye-candy' features
 * Colour configurations
 * Skins
 * 3D editing mode (including slopes and translucent textures)
 * Uses wxWidgets for the user interface
 * Easy line and rectangle drawing

SLADE 3 does not currently feature a map editor yet, as development prioritizes the lump management features with the reasoning that Doom Builder 2 is available in the mean time.
