In addition, there are currently 2 settings that can only be manually changed in your \$Home/.bcast5/Cinelerra\_rc file and then done so by very careful editing. These include FAST\_SPEED and SLOW\_SPEED which allow you to modify the default 2X speed of \textit{Fast forwward} and the .5X speed of the \#2 keypad for \textit{Slow speed forward play}.
For example, adding the 2 lines FAST\_SPEED 4 and SLOW\_SPEED .2 to the end of the Cinelerra\_rc wile will result in playing at 4X faster and 5X slower.
+Another example of user modifiable settings involving the plugins menu in the Resources window, can be found in \nameref{sub:expanders_plugin_subtrees}.

\CGG{}’s default setup is in the file \texttt{\$CIN\_DAT/expan\-ders.txt} but if the user wants their own specific setup and if the file in \texttt{\$HOME/.\\bcast5/expanders.txt} exists, it will take precedence.
If there are recommendations for other relevant categories, they can be added. The subtree structure is applicable to any of the \textit{Video Effects/Transitions} or \textit{Audio Effects/Transitions}. You can not sort once an expansion is in effect (figure~\ref{fig:expander}).
-The \texttt{expanders.txt} file has very specific requirements. The most specific is that there are no blanks -- you must use tabs only. A \# (pound sign) can be used in column 1 to indicate a comment. Here is a short example:

+NOTE: The capability to put the expanders.txt file in \texttt{./bcast5} (see \nameref{sec:bcast5}) allows for customizations such as grouping favorite plugins in one section so that they can be recalled more quickly. For this purpose, the \textit{Favorites} section has been included at the top of Video Effects, the contents can be changed as desired. Once your modified file is saved to hard disk as \$HOME/.bcast5/expanders.txt it will remain in use on every update as long as you do not delete it or remove the .bcast subdirectory.
+For users running \CGG{} using the AppImage, to make an initial copy of expanders.txt, execute the
+following lines on /tmp:
+\begin{lstlisting}[numbers=none]
+ git clone --depth 1 "git://git.cinelerra-gg.org/goodguy/cinelerra.git" cinelerra5
+ cp /tmp/cinelerra5/cinelerra-5.1/expanders.txt $HOME/.bcast5/expanders.txt

To build findobject and the other plugins using OpenCV, access the src using git:
\begin{lstlisting}[style=sh]
-git clone -depth 1 "git://git.cinelerra-gg.org/goodguy/cinelerra.git" cinelerra5
+git clone --depth 1 "git://git.cinelerra-gg.org/goodguy/cinelerra.git" cinelerra5
