Checked it out and it seems like they took a (very) small subset of what emacs can do and re-implemented it. In order: Edit multiple documents: Multiple buffers with buffer menus, buffer-name completion, etc. Syntax highlighting: See font-lock-mode Multi-level undo/redo: See emacs undo. Emacs does lack in the redo area though... Directory tree view window: See dired Find and replacs: C-M-$ or if you like regular expressions, M-x query-replace-regexp column mode editing: See rectangle manipulation commands in emacs. Natural word wrapping: See auto-fill-mode Spell checker: See flyspell-mode and flyspell-prog-mode which only spell shecks inside comments and program strings. User tools and macros: See elisp: One of the most advanced programming languages, integrated right into the editor. Furthermore, comint can be used to call any other program and manipulate output. Etc...: See emacs packages. Etra: A complete programming language instead of the restricted macros in Crimson. Since elisp is turing complete, practically anything is doable, programs like GNUS, etc... So... try emacs and see if you like it.
