Thanks for the kind words!

I can see how this could be useful.  It probably wouldn't be too difficult
to make a simple display for this.

I've considered adding a similar feature.  The problem is that Viewglob
doesn't always know perfectly where the cursor is on the command line (it
can only guess using heuristics based on terminal input).  Still, it's
usually pretty good.  I can at least try it to see how useable it is.

FYI, you can make hidden files visible by adding them to the display mask.
By default the displays use a mask of "*", thus listing all non-hidden
files.  To also list hidden files, change the mask to ".* *" by typing:

	<Ctrl>-<G> <.> <*> <SPACE> <*> <ENTER>

Thank you for the input, David!  When I get a little time I'll see if I
can put your ideas into action.
