The Oxygen desktop theme is used by Plasma and other KDE Software.

Low resource Window manager ideal for older PCs. It uses a minimum of external libraries, and thus very little memory. It allows new xterms to be spawned by clicking the middle mouse button but does not itself include icons, button bars or root menus.

It's an interactive Unix filter for command-line that can be used with any list; files, command history, processes, hostnames, bookmarks, git commits, etc.

Handles account setup of e-mail accounts for KDE PIM applications.

Trac uses a minimalistic approach to web-based software project management. Its mission is to help developers write great software while staying out of the way. Trac should impose as little as possible on a team's established development process and policies. It provides an interface to Subversion (or other version control systems), an integrated Wiki and convenient reporting facilities. Trac allows wiki markup in issue descriptions and commit messages, creating links and seamless references between bugs, tasks, changesets, files and wiki pages. A timeline shows all current and past project events in order, making the acquisition of an overview of the project and tracking progress very easy. The roadmap shows the road ahead, listing the upcoming milestones.
