I have an old Mac OS9 program (circa 1991-1995) called IN CONTROL that was made by the Attain Corporation and written by Robert Alpert, Dan Chadwick and Steve Troppoli. This is a great organizer program which I still use because it works so well. Unfortunately, IN CONTROL never made it to an OSX version and I believe 3.5 may have been the sunset release. It's also my understanding that IN CONTROL is currently the property of FileMaker Inc. which - for whatever the reasons - decided to no longer continue it's development. A couple of reviews of IN CONTROL from 1993 and 1994 can be found at:
The closest thing I've seen to IN CONTROL is OmniOutliner. A lot of the "look" of OmniOutliner is very much like IN CONTROL, though I don't feel it's the same intuitive experience - or more likely, I'm simply not as familiar with OmniOutliner and so I prefer sticking with what I know.
Like IN CONTROL, OmniOutliner is still a desktop based program. Given my preference to Web based applications (Yahoo! Mail, Google Docs etc.) I find having something like OmniOutliner tied down to my home machine very limiting. What I'd really like to have is access to something like an online IN CONTROL program. Anybody know of anything?
