@ -1094,7 +1094,7 @@ The lists of captured memory allocations are displayed in a common multi-column
The allocation's timing data is contained in two columns: \emph{appeared at} and \emph{duration}. Clicking the \LMB{}~left mouse button on the first one will center the timeline view at the beginning of allocation, and likewise, clicking on the second one will center the timeline view at the end of allocation. Note that allocations that have not yet been freed will have their duration displayed in green color.
The memory event location in the code is displayed in the last four columns. The \emph{thread} column contains the thread where the allocation was made and freed (if applicable), or an \emph{alloc / free} pair of threads, if it was allocated in one thread and freed in another. The \emph{zone alloc} contains the zone in which the allocation was performed\footnote{The actual allocation is typically a couple functions deeper in the call stack.}, or \texttt{-} if there was no active zone in the given thread at the time of allocation. Clicking on the zone name will open the zone information window (section~\ref{zoneinfo}). Similarly, the \emph{zone free} column displays the zone which freed the allocation, which may be colored yellow, if it is the same exact zone that did the allocation. Alternatively, if the zone has not yet been freed, a green \emph{active} text is displayed. The last column contains the \emph{alloc} and \emph{free} call stack buttons, or their placeholders, if no call stack is available (see section~\ref{collectingcallstacks} for more information). Clicking on either of the buttons will open the call stack window (section~\ref{callstackwindow}). Note that the call stack buttons that match the information window will be highlighted.

The \emph{\faAlignJustify{} Call stack tree} pane is only available, if the memory events were collecting the call stack data (section~\ref{collectingcallstacks}). In this view you are presented with a tree of memory allocations, starting at the call stack entry point and going up to the allocation's pinpointed place. Each level of the tree is sorted according to the number of bytes allocated in given branch.
Each tree node consists of three elements: the function name, the source file location and the memory allocation data. Clicking the \RMB{} right mouse button on the source file location will open the source file view window (if applicable). The memory allocation data is either yellow \emph{inclusive} events count (including all the children), or the cyan \emph{exclusive} events count. There are two values that are counted: total memory size and number of allocations.

\item Zone trace, taking into account the zone tree and call stack information (section~\ref{collectingcallstacks}), trying to reconstruct a combined zone + call stack trace\footnote{Reconstruction is only possible, if all zones have full call stack capture data available.

\subsection{Call stack window}
\label{callstackwindow}
This window shows the frames contained in the selected call stack. Each frame is described by the function name and source file location. Clicking the \LMB{}~left mouse button on either the function name of source file location will copy the name to the clipboard. Clicking the \RMB{}~right mouse button on the source file location will open the source file view window (if applicable).

Clicking the \RMB{}~right mouse button on the source file location will open the source file view window (if applicable, see section~\ref{sourceview}).
Sometimes it may be more useful to have just the function address, instead of the source file location\footnote{It can pinpoint the exact assembly instruction which caused the crash.}. This can be achieved by selecting the \emph{\faAt{}~Show frame addresses} option.
\subsection{Source file view window}
\label{sourceview}
In this window you can view the source code of the profiled application, to take a quick glance at the context of the function behavior you are analyzing.

]{Important}
Source file view works on the local files you have on your disk. The traces themselves do not contain any source code! This has the following implications:
\begin{itemize}
\item The source files can only be viewed, if the source file location recorded in the trace matches the files you have on your disk.
\item \textbf{The displayed source files might not reflect the code that was profiled!} It is up to you to verify that you don't have a modified version of the code, with regards to the trace.
