DynarchMenu is a cross-browser and cross-platform DHTML menu, featuring keyboard navigation, high-quality CSS color themes (skins), unlimited menu depth, horizontal or vertical display, context menus, timeouts, and more. The menu is defined in plain HTML as nested lists, as opposed to the pure JavaScript setup that is used in most menus. Aside from being more friendly to search engines, this has the advantage of being extremely easy to generate and degrading well even to non-JavaScript browsers. The code is small and highly optimized for speed.
gmrun provides a small window which lets you launch programs by typing their names. It features tab completion similar to bash or Emacs. It can complete program names from $PATH, or if the command starts with "/" it will complete file names. It provides a command history of configurable size, as well as the ability to perform forward/backward searches through the command history. gmrun was developed as a replacement for the Gnome Run program.
The Coolest DHTML Calendar is a DHTML calendar widget that works with IE >= 5.0, Mozilla, Netscape >= 6, all other Gecko-based browsers, Opera 7, Konqueror, and Safari. It comes with eight color themes, and doesn't use frames or external windows, but uses Web standards and is lightning fast. Keyboard navigation is allowed, and it can optionally show a time selector.
Xuheki is a fully featured email (IMAP) client for the Web. It looks and feels like an application rather than a Web site. It is fast, clean, and features no page reloads. It supports multiple users per installment, multiple IMAP servers per user, and multiple folders per IMAP server. It also supports text or HTML email, attachments, inline images, printing, and more. It has an "AJAX" interface that could compete with desktop-based mail user agents.
Ymacs is an extensible AJAX text editor aimed for programmers. It's similar in spirit, features, and key bindings to Emacs: it supports multiple buffers, split frames, dynamic completion, multiple keymaps, and Emacs-like undo queue and kill ring. And of course, Emacs-like key bindings for all of that. It provides syntax highlighting and automatic indentation for a few programming modes, currently JavaScript, XML, CSS, and Lisp. Ymacs is based on the DynarchLIB AJAX toolkit and currently runs on Firefox (support for more browsers is planned). It's implemented in JavaScript and can be programmed in JavaScript as it's running.
