Consider forking the software yourself Dave; that’s what a fork is. If AxCrypt were to add the feature it wouldn’t be a fork, it’d be an official feature.
It’s something that’s only asked for by a minority of the overall userbase so until people start splashing the cash, the development team only have finite resources and they need to focus on getting the software rock solid and reliable before even contemplating adding new features.
If peopl want the individual password feature then version 1.7 is still out there and, that old model, is still causing many problems for people, Version 2 is a breath of fresh air. Those determined enough to use another model have version 1.7.
