The content of the lines in the output section are not copyable.
If i get error like:
"pdflatex> pdflatex.exe: The memory dump file could not be found." , i have to TYPE OUT every message...
It is possible to select the message line, but not possible to copy the content. nice idea.
I know, the copy feature (in a textarea) is an unusual use case, but it could facilitate the searching for solution via google...
