In original vDos and earlier versions of vDos-lfn, the first character in each line of the screen starts exactly at the window border, and apparently there are people who dislike this. So I just added the feature to set border or edge padding in the text-mode vDos-lfn window in the latest build of vDos-lfn (i.e. build 2016.09.01). Now you can change the border padding via the BORDER directive in config.txt, e.g. BORDER=20. Hope this will be useful.
As always, the download address for the latest ZIP package of the 2015.11.01 branch of vDos-lfn is at the URL:
