The new Auto Move Older screenshots feature is a nice one for sure.
But in my opinion it is inappropriate for it to be enabled by default. I found this out by surprise after upgrading ScreenshotCaptor recently. I guard my data very carefully and found this an unwarranted manipulation of my data without my approval.
I also have Picasa and some other photo programs that rely upon my images being in certain folders and structures, so for ScreenshotCaptor to suddenly take my screenshots hostage and move them to a new series of folders , presents a risk to my configuration.
I hope you will reconsider auto-enabling this option. Or at least post a one-time dialog upon upgrade, to notify users of this change in folder management.
