JMGRIFF  You can add whichever search engines you want - so far I've added MacUpdate, PubMed, GoogleUK ......  
(Version 1.0.1)

JMGRIFF  I bought EarthDesk v1.0 and then the paid upgrade to 3.0, and I like the program a lot ... but I cannot see why I would pay $10 to upgrade again to v4.0 ?   
(Version 4.0)

JMGRIFF  This is just what I needed for using my C2D iMac at night - much more adjustment than is possible in system preferences.

Thanks to the developer for making it.  
(Version 1.1.1)

JMGRIFF  I stand by what I said originally. I've been following the situation of orthodox file managers on OS X for a number of years (muCommander, MC in terminal, Disk Order). Many of the people interested in orthodox file managers will have previously used Norton, Midnight or Total Commander, applications that have characteristically high levels of keyboard control.

I'm not saying you shouldn't be able to use the mouse, but good keyboard accessibility would greatly raise this applications usefulness.  
(Version 1.2.1)

JMGRIFF  I actually meant "Look at *Midnight* Commander to see what is possible" as far as keyboard control is concerned.  
(Version 1.2)

JMGRIFF  I like orthodox (2-panel) file-managers and was therefore happy to see that this program is being actively developed.

IMO the best file-managers can be driven completely from the keyboard. What Xfolders needs most is more keyboard shortcuts ... especially for the options in the Path Navigator contextual menu (e.g. to swap source/destination and 'Other Folder'). This applies equally to the favourites manager, where it doesn't seem to be possible to select favourites by the keyboard alone.

I suspect most of the potential users of this software don't want to use a mouse ...... ;) Look at the original Norton Commander to see what is possible.

Comparison to PathFinder is inappropriate in my view. With the dire state of the Finder, what Mac OS X needs is a fast, lean and mean application that confines itself to *managing files*. Xfolders could be that app if the user-interaction was made more efficient and intuitive.
