Folding@Gnome project is an applet is a GUI that keeps track of the background protein folding progress done by Folding@Home

The Folding@Gnome applet is merely a GUI in which you can adjust your Folding@Home settings and view the folding progress. Folding@Home is a background process that uses spare CPU cycles to calculate the folding of proteins. For more info, please visit Stanfords Folding@Home homepage.

GNU/Linux Desktop Testing Project (GNU/LDTP) is aimed at producing high quality test automation framework and cutting-edge tools that can be used to test GNU/Linux Desktop and improve it.
GNU/Linux Desktop Testing Project uses the "Accessibility" libraries to poke through the applications user interface. The framework has tools to generate "AppMap" by reading through the user interface components of an application. The framework also has tools to record test-cases based on user-selection on the application.
GNU/LDTP core framework uses "AppMap" and the recorded "test-cases" to test an application and gives the status of each test-case as output.
As of now, GNU/LDTP can test any GNOME application which are accessibility enabled, Mozilla, OpenOffice.org, any Java application (should have a UI based on swing) and KDE 4.0 applications based on QT 4.0 (based on the press releases by KDE).
We encourage you to join the project and help us to create robust, reliable and stable test tool/framework for Linux Desktops.
Main features:
- LDTP concepts are derived from Software Automation Framework Support
- LDTP supports verification of actions performed (GuiExist, VerifyState, etc) - API Reference
- Writing test scripts are very easy, the script writer need not know about the object hierarchy
- CPU / Memory performance monitoring of application-under-test can be measured - Class pstats
- From the XML log, we can gather HTML report using XSLT
- Group based execution, which provides precise control on the flow of test-script execution - Gldap XML
- Scripts can be written as a reusable component and for that the datas can be stored / retrieved in XML - Data XML
- User-friendly Text Editor with syntax highlighting for generating and grouping test data Howto use LDTP Editor
- Objects are identified both statically and dynamically
Enhancements:
- Now automation scripts can be written without using time.sleep.
- A particular object and its child can be remapped in a window.
- Memory leaks were fixed.

Lucidity hopes to become the next generation graphical user interface focused on speed and usability.
Lucidity is being developed in Ruby and at this point Im the only developer. Although not much information is given on this site (right now, that is) I have a pretty good idea of where Im aiming towards with this interface.
Enhancements:
- This is a (testing only) local chat application that allows two or more instances of a chat application to communicate with each other.

Tasty Menu project is a KMenu replacement aiming to provide the maximum usability, or at least to be a testbed for usability concepts and ideas for a future kmenu replacement.
The left part of the menu is very similar to the Novell idea (http://www.novell.com/products/desktop/preview.html): you have a search box that is always selected when the menu is opened (the search result are displayed in the leftmost listview), followed by a combobox that decides what the following listview: favourite applications (default), most used applications, recently used applications and recent documents.
The right part contains the whole kmenu and takes the aspect from KBFX (http://www.kbfx.org), the middle column contains the top level categorization (plus in the current kmenu arrangment there are also the control center, home folder and find files, but i think there should be present only categories). in the left-most listview there is the content of the category currently selected in the middle column. I think in this way even if it has the same number of items it _appears_ less huge than with a popup menu/submenu structure.
every items have two row, for the name and for the description, in order to make a more it more informative. On each selected item appears an action icon on the right, at the moment they are "add bookmark" on application icons and "remove bookmark" on favourite apps list.
The bottom buttons are the usual switch user, lock session and logout. In a first time I didnt want to put them, I tought that these function should be delegate to another applet like http://kde-apps.org/content/show.php?content=26150 , but it seems that the multiple menus concept its a thing that doesnt work very well in practice, it needs more real-world testing.
The left-most btton contains the user name and icon, and clicking on it it opens the kcm used to edit the users profile. I know it seems silly, but Its only an experiment, probably it will be merged with the switch user button.
Enhancements:
- "Add to desktop" option in menuitems
- Drag and drop from menu to desktop
- Option to set different icons sizes in the three columns
- the button text label should always be of a visible color
- most used/recently used applications list updates in realtime
- clear most used/recently used applications list
- (warning1: deleting one list deletes also the other)
- (warning2: if you use opensuse you must have kickoff reverted to classic kmenu in order to use the recently used/most used lists)
- updated russian and german translations
