Yes, you can access the list of projects and contributions by clicking "Edit Project..." from the "Applications" menu inside Wiki-OS.

For example, the window manager and the taskbar source code can be found in the project named "WindowManager".

You can also see the list of contributions (sorted by date) by launching the "History" application. For the list of changes of a specific project, open a project in the Code Editor and then click "Social" -> "View history of changes".
