Would you consider adding a couple of Wizards to Hurricane?:
LAYER COLOR (TRUE & ACI) -Perhaps import the layer list from a text file
LAYER PLOT STYLE ( Cover CTB and STB Named Plot Styles) -Perhaps import the layer list from a file
LAYER RENAME -Perhaps import existing and new layer names from 1 or 2 lists
LAYER TRANSLATE -User creates a layer translation CAD standard file, from the Autocad Cad CAD Standard wizard -Hurrican Wizard wraps / points to that files and initiates the translation of the Cad drawings in the Que List.
CAD FILE CLEANUP WIZARD -Hurricane could present a dialog of cleanup tasks that the user selects -Purge -Audit -Initiate a user-defined lisp -Zoom E -Update a Date ( a tag or attribute of sorts) >>>Basically provide a wizard to assist with drawing cleanup efforts.
Adding Wizards would bring a whole new set of functionality to the app Less Debugging for the user :)
