Are these settings persisted on their server? Does Dropbox know to not sync those files on a new computer, or do you have to set those settings everywhere? If not, if this works like Selective Sync (which is a local setting), then you can end up accidentally syncing those files from new computers. And is thus not equivalent with a .gitignore. Also does it support glob patterns? Why couldn't they do a .gitignore that syncs along with your other Dropbox files and be done with it?
