First of all, let me say that I did a test drive with this software once and if it wasn't for DOpus, this one would have won the title of my best file-manager.
XYPlorer is a well known name in file-manager land...but let's be honest, it isn't much of a name. I understand the need for change. FleXYfile is more descriptive and still has the XY reference, but that doesn't mean that it is a good name.
Unfortunately I cannot come up with a better name that includes the XY reference...at least not at this time of night (it's about 04:00 at the time of writing)
