About using the selective sync dialog: it takes me about 5 minutes to just load the folder list in the GUI, and it&#x27;s on a quad-core Macbook Pro with 120 Mbps internet.<p>I believe a perfect solution for power-users would be a support for &#x27;.nodropbox&#x27; files, which would disable selective sync for a given directory and it&#x27;s subfolders.<p>An even better idea would be &#x27;.dropboxignore&#x27; files, using the same syntax as &#x27;.gitignore&#x27;.
