There may be hope after all! The outliner Opal seems to be on the right track.
What is most encouraging, is that David Dunham (Opal’s software designer), has already sent me two emails regarding his product and as a bonus – owns IN CONTROL too, so he knows what I’m talking about! I’m hoping David adds columns soon as they’re absence makes Opal difficult to want to use. Ideally, I hope over time he can incorporate the best features of IN CONTROL into Opal. If he does, I’m confident he’ll have a great product.
