It can be next to the link View Log and button Clear results. 
1. Since window with the log is not having clickable stacktrace to land me directly to the code, I click View Log and than click Copy to Clipboard to be able to paste in a separate text editor and read the stacktrace to navigate to the code. Having link will save me one click.
2. Another reason to not use this window is that it is not dockable and locks my access to the IDE under it.
