Why are you developing two versions of the windows app? The recent 1Password 6 Beta notes that now much of the code base between the two apps are shared, but you still have two versions on Windows with slightly different characteristics.
Since 1Password 6 will run on Windows 7 , 8, 8.1, and 10, why even have the UWP app? It would really make the Windows family of products much easier to understand as you would have the current stable (if old) version 4, then version 6 after it gets out of beta.
Doesn't having 3 versions, all of which are in different states of development drive your Windows developers nuts?
P.S. Former LastPass user. Love 1Password and are a Windows + Android family. I have investigated others in the past few months, such as Sticky Password, Dashlane, KeePass, EnPass. 1Password just makes sense. Version 4 works better than all of those even with the older code.
