Directory Opus will not property open the Command Prompt "here" when using a network UNC.
I believe this could be easily implemented with a simple logic:
When the current path is a UNC, then replace the standard "cd" (change directory) command to the "pushd" command, for example:
Existing method:
cd \local\path
New method for UNC's:
pushd \\server\share\remote\path-as-full-unc
