I would like Zotero to automatically resolve most conflicts to the best of its ability. Often, sync is hung up on conflict resolution. When I go through the necessary series of dialogues to resolve the conflicts, typically I can see no difference in the fields presented. Almost always, I'm happy with the "Merged Object". As a consequence, I just click Next again and again to get done. The very small differences that Zotero is finding really don't matter to me, and the requirement for me to confirm each resolution just gets in the way of syncing and of using the database.
I do agree, though, that a "do for all" or so option for merge conflicts would be a good idea.
The solution here is really to find the cause of conflicts (since they _should_ be few and far between) and prevent that instead.
Did you experience sync errors? <- Yes, that is the problem - orange icon to left of sync icon is present, indicates errors, instructs to run sync to resolve them, then I get long series of resolve conflict dialogs.
Are you working on your library from multiple computers? <- Yes
What conflicts do you see (attachment timestamps, items added/deleted, date modified timestamps, fields you actually changed on multiple computers, etc.)? <- this is part of the problem - usually the differences are invisible to me; when I get to this point next (after working on another computer tomorrow, most likely) is there some useful way for me to capture the state of conflict between the local machine and the Zotero server that could help identify the source of the problem? I really can't see it.
Thanks for your thoughtful attention.
