I recently updated my machine and had to re-install VD. Unfortunately, I lost all of my customizations. The settings are stored in the registry; it would be nice to have and export/import settings feature.
regedit.exe /e settings.reg "HKEY_CURRENT_USER\Software\Typz Software\Virtual Dimension"
you can export with previous command line, and import by double-clicking (when VD is not running) the produced "settings.reg" ;)
