I'd really like to set DO to open all folders that I select from the shell (ie. on the desktop, in the start menu, or from the command line through litestep) in new tabs inside my current lister. Ideallly I'd like to only have one lister open, and use it with tabbed browsing much like opera or firefox. I've read all the help docs, but I can't find a way to do this. Any help would be appreciated.
This isn't supported and has a few issues but you might want to experiment with the registry setting mentioned in this thread:
