GSmartMix provides a smart control of the audio on GNOME. There is also an applet which allows manual adjustment of sound per application. Each application using GStreamer can benefit from this project without any intrusive patch. Other applications should implement the D-Bus interface proposed with GSmartMix to be seen by the smart manager.

gjots lets you organize text notes in a convenient, hierarchical way. It can be used for notes, jottings, bits and pieces, recipes, and even PINs and passwords, using encryption. It can also be used to "mind-map" larger compositions like manuals, Web pages, articles, etc. It is a bit like the KDE program "kjots", but uses the GTK library and supports a hierarchy of folders. Files can be output to HTML with an automatic table of contents or to docbook XML. Encryption is supported with ccrypt(1), gpg(1), and openssl(1), so that musings can be kept private.

IPTEditor intends to ease the task of managing/editing iptables rules. It presents an intuitive graphical interface that organizes iptables tables as tabs of a notebook, each of which, in turn, organizes their chains in notebooks tabs. Each rules tab contains a list made up of rows (rules) or item columns ordered according to their occurrence. The items in the rows can be edited by appropriate forms, such as through dialogs for targets and criteria (modules), edit fields for network addresses, and selection boxes for actions and protocols, among others.
