 \begin{itemize}
 \item \emph{\faExpand{} Draw empty labels} -- By default threads that don't have anything to display at the current zoom level are hidden. Enabling this option will show them anyway.
 \item \emph{\faHiking{} Draw context switches} -- Allows disabling context switch display in threads.
+\item \emph{\faMoon{} Darken inactive thread} -- If enabled, inactive regions in threads will be dimmed out.
 \item \emph{\faSlidersH{} Draw CPU data} -- Per-CPU behavior graph can be disabled here.
 \item \emph{\faEye{} Draw GPU zones} -- Allows disabling display of OpenGL/Vulkan zones. The \emph{GPU zones} drop-down allows disabling individual GPU contexts and setting CPU/GPU drift offsets (see section~\ref{gpuprofiling} for more information). The \emph{\faRobot~Auto} button automatically measures the GPU drift value\footnote{There is an assumption that drift is linear. Automated measurement calculates and removes change over time in delay-to-execution of GPU zones. Resulting value may still be incorrect.}.
 \item \emph{\faMicrochip{} Draw CPU zones} -- Determines whether CPU zones are displayed.
