\markboth{Limitations}{}

\begin{itemize}
\item The sizes and positions of objects cannot be changed by direct mouse manipulations.

\item \usecase{Copy}, \usecase{paste}, \usecase{cut}, \usecase{undo}, and \usecase{redo} work only with the EW, not the canvas.

\item One cannot do \usecase{search} and \usecase{replace} in the EW.

\item Font information of the text is not saved.

\item One cannot directly manipulate constructs, \eg\ \token{for}, \token{if}, and block, on the canvas.

\item One cannot output pictures in a standard graph format, \eg\ \program{gif} and \program{png}, or print from \program{WD-pic}. You have to feed the saved \program{pic} file to \program{pic} or to another program that is capable of dealing with \program{pic} input.

\end{itemize}
