AllTray is a program you can use on UNIX and UNIX-like systems, such as GNU/Linux or FreeBSD, running the X Window System. It is used to “dock” application software into the system tray (also known as the “notification area”). AllTray aims to be standards-compliant and work with any desktop environment/window manager+system tray combination that is also standards-compliant.
pin 'em up is a tool for placing small notes/post-its (e.g. TODOs/reminders) on your desktop and organizing them in various ways (categorize, hide, upload, export, etc.). Due to platform independence, the notes can also be shared on different operating systems. It features system tray integration, freely placeable notes, many possibilities to customize the note design, (nearly) unlimited user-defined categories, fast switching between categories (e.g. "home" and "office"), automatically saving notes to a file, an open file format (XML), server upload/download functions (FTP and WebDAV), and exporting notes to a text file.
The Launcher is an innovative GNOME panel applet or stand-alone application launcher automatically adapting to your habits. The ultimate goal is to make it possible to run any application with as few clicks as possible. This means tracking your favorite applications, and not forcing you to mark or organize them by hand. Preferences change with time, and The Launcher responds to that automatically. It delivers a simple, clean, and usable interface with advanced features like 'search as you type' and 'smart search', and requires zero configuration effort. It should be especially handy on touch screens and in keyboard-only scenarios.
Javeau is a small tool meant to provide an easy way to create and use encrypted directories, using strong cryptography and a simple interface. It works under Java 6. Data stored in these folders are encrypted and safe (using 256 bit encryption); they can be accessed only by the user (by providing the password used to create the folder), and their integrity is checked to prevent data tampering. The application sports a convenient file-manager-like interface, is very fast and small, and is completely cross-platform: you can access your encrypted storage everywhere you can run a Java 6 VM.
Envoy is an "open and display things" library. It provides an interface for storing file associations and launching files based on those associations. This comes with a wrapper program to enable desktop users to benefit from the file associations without developers adding explicit support. It also supports opening any URI transparently, as long as the corresponding protocol support exists: applications that want simple read (and write, depending on the protocol) access to files, wherever they are, can use the envoy API to do so.
X Persistent Remote Applications (xpra) is "screen for X". It lets you run applications remotely (like ordinary X or VNC), but unlike ordinary X, these applications are "persistent" if you lose your connection, or even if you want to switch to another computer. Also unlike VNC, they are ordinary applications on your desktop managed by your window manager, not trapped in a box.
