Periodically I look through my Dropbox folders and find conflicted copies. I understand how they can occur, but at the time I don't realize for example that another program that accesses the same file is open. If I knew it was open the conflicted copy wouldn't occur, and there is no notification to my knowledge. I may find a conflicted copy months later, which is useless in maintaining data integrity. I'd like to make a request for a notification system that lets you know immediately that you've created a conflict. It is unbelievably easier to fix it at the time, rather than later. This is an incredibly important enhancement to Dropbox to keep our data safe.
