Xtla is the Emacs front-end to the GNU Arch revision control system. It provides user-friendly wrappers for tla native commands and some higher level features such as the bookmark manager. The main features are a PCL-CVS-like interface for tla inventory and tla changes, an archive browser, good integration in Emacs, a bookmark manager, integration with ediff, Emacs's graphical diff tool, an interface to view missing patches from all your partners with a single command, and an Emacs mode for arch-related files (log files, =tagging- method).
Easymacs is an easy-to-learn, one-size-fits-all configuration for new users of GNU Emacs. It sets up key bindings that conform to a common denominator of the Gnome/KDE/OS X/Microsoft Windows human interface guidelines, and provides function-key bindings for other powerful Emacs features. It is fully documented, and the new user can productively edit text right away, without going through the Emacs tutorial. Many commonly-used functions can be accessed without having to learn the "chords" or multiple keystrokes that Emacs uses by default.
enotes is a small GNU Emacs script to handle appointments. It stores a list of notes, each with a title, a date, a warning date, and optionally a long description and a reference file. A window pops up when a warning time is reached. It is simple (more than calendar and others), yet reliable and very practical.
Aquamacs is a Mac-like version of the powerful Emacs text editor that runs as a standard OS X application. It features extensive customization that enables it to conform better with Apple's standard Human Interface Guidelines (HIG) than standard versions of the editor do. It provides a more Mac-like user experience than Carbon Emacs.
refdb-mode is a minor mode for Emacs that implements an interface to RefDB, a reference management and bibliography tool for SGML, XML, LaTeX, and Muse documents. It integrates nicely with psgml, nxml-mode, AucTeX, and muse-mode. refdb-mode provides the complete functionality of the RefDB command line clients from a graphical interface. You can add and edit references, notes, and styles, run queries, and insert the results as citations into your DocBook, TEI, LaTeX, or Muse documents. You can also look up cited references in the database right from your document. You can create, transform, and view these documents with a mouse click. This amounts to an integrated authoring environment for markup languages with reference management and bibliography support.
Versatile Cursors for GNUemacs is a set of emacs commands managing an "item" cursor (e.g. a word, expression, sentence, or defun). It quickly re-assigns the cursor keys between these as needed. Built on this are high-level actions such as converting code blocks to separate functions. This provides elegant and concise editing, and is pedal- and voice-friendly.
