Many times text files are changed by appending content. There should be a mode that maintains the distance of the vertical scroll in relation to the bottom of the scroll bar, rather than the top. This will allow a user to focus on a specific section of content that is being added to the text document (even if it is not added to the end of the document).

I have added a "scroll to bottom" feature for text files that will scroll to the bottom of the file when the text file is changed. This should fulfill the needs of appended text files such as log files.
