At first, i neglected some features of visual mode (such as texture dragging.) It can do anything (except for get you a sandwich). It's great for texturing. However, it's not good for underwater maps, as you can still suffocate while texturing. Just don't stay underwater for very long.
Visual Mode is a plugin that allows you to texture maps in Aleph One. It supports almost all features of Forge's visual mode, plus OpenGL, multiple texture sets, and more. Requires Aleph One 1.7.
