LogTail follows changes to an opened log file by default. But, you can stop or start the tailing operation by toggling
the switch at the top of the document.
When the switch is in "On" position , changes to the log file done outside of LogTail
are detected and the new data is appended to the end of the document window.
If the switch is in "Off" position , external changes to the log file are not detected and
the view is not updated until Tailing is turned On again.
