Well, with respect to making a stack active, scratch what I said about opening it up. The only way that I know of to definitively select the active stack is to use the Selection / Add Selection to Stack menu. I've noticed this past week that opening up a stack doesn't always make it the active stack. Yes, I do wish this were easier.....for me that would be a dropdown from the stack tool button or some kind of shortcut key from the library. To my untrained (and non-programmer) eye, the active stack is almost a randon selection. Right now, mine is stuck on a stack I haven't actually used in several months. Change it, close Accordance down and open it again and its back to where I started.
Since you've mentioned syncing, what are you using to sync Accordance between machines, and what OSs are involved? I use Dropbox and am syncing macOS and iOS; sometimes it can be difficult to actually delete something from both the local machine and the sync. Dropbox did a major revision of their Mac client a month or so ago, and it seems better to me, but I too sometimes struggle to really delete an item that is being synced by Dropbox.
