The only feature I want in addition to what Dropbox already gives me is a little box I can check that says &quot;Never Delete Anything.&quot;<p>That&#x27;s it.<p>Just never give me the option of permanently erasing an entire folder of photos from every machine I&#x27;ve ever owned just because I mess up your wacky Selective Sync workflow.<p>I understand that there exist people who actually want all their machines to sync destructive changes, but I&#x27;ve never met one of them.  More often, I see people lamenting that they deleted something important a year ago, thinking it was still backed up, but now it&#x27;s gone.<p>So yeah, you&#x27;re not a backup service, you&#x27;re just sync.  I get that.  But please please be a little <i>less</i> syncy and a little more backupy and you&#x27;ll fit the worldview of a lot more people.<p>It sounds like this is a step towards this (and four thousand steps past it), so at least we&#x27;re getting close.
