Xfce Embed Plugin enables the embedding of arbitrary application windows into the Xfce panel. The window is resized into the panel space available, and the associated program can be automatically launched if it is not open. Example uses include embedding an instant messaging buddy list, a mail client's new mail ticker, a simple media application, or a fancy clock or timer. Combining with Xfce's ability to auto-hide panels can make this very convenient.
Abmash provides Web application automation based on visible rendered output. It is all about interacting with a browser as humans would do, including AJAX and forms. It lets you perform tasks like "Click the red button", "Give me all text elements directly below an image", or "Click 'Login' and wait until the login form is loaded, then type in my credentials and submit the form".
Fish Sync is a file syncing application. It can transfer multiple folders between multiple machines, keeping these folders synchronized. The Fish package does not need to be available on each machine in the group, only on the machine initiating the synchronization. The Fish program is separated into two pieces, one which does the work in the background, and the other a frontend configuration tool. This separation allows the Fish service to be run on servers where a GUI interface is not desired.
