I am a packrat with DevonThink. I save everything there, but don’t need the same columns when viewing, for example, email versus documents.
I have several work apps that feature saved column views, which would be INVALUABLE to me in DTPro!
Please?? 
I don’t know whether or not that will happen.
I’ve usually got multiple view windows open, configured with different columns.
The only workaround right now would be to use multiple databases.
