With respect, I think this is beside the point. Aside from my belief that it would be unrealistic to expect IPS to collaborate wtih any one developer (even with such powerful apps as these), my valid complaint has nothing to do with Kevin's relationship with IPS - it has to do with the failed obligation to his paying customers. There's nothing stopping him from continuing development on these apps and making them available for purchase from this site - which, after all, is dedicated to the very apps we're talking about! However, not only has he chosen not to do so - he has left his customers in the dark. And I get it - priorities change, people get new jobs, etc. - however, I should not have to leave 6 messages across different platforms to be told that there will no longer be any development whatsoever, after the last message he released was that critical compatibility upgrades would be made.
If you don't believe me when I tell you what Kevin told me (he said "it just doesn't make sense at this point" or something to that effect), proceed at your own risk. I'm here only to seek help on uninstalling Collabs, which is the only thing that won't go quietly. And I just turned 50 and I'm not a developer and have no time to waste (it's a waste for me) on doing something that isn't my chosen vocation.
