I have an outline with several columns, and sometimes I'd like to hide the columns. Is there a way to do this? If not, please consider adding this to 4.0.

It is possible to toggle the visibility of columns with an Applescript, which you could place in the toolbar.

Something along the lines of:

tell application "OmniOutliner Professional"
	set intWidth to 80 -- Adjust this value
	
	tell document of front window
		repeat with iWin from 3 to count of columns
			if width of column iWin ≥ intWidth then
				set width of column iWin to 0
			else
				set width of column iWin to intWidth
			end if
			
		end repeat
	end tell
	
end tell
