You might see that the Dropbox Community team have been busy working on some major updates to the Community itself! So, here is some info on what’s changed, what’s staying the same and what you can expect from the Dropbox Community overall.
As an admin setting, it would be useful to have an option that resets files that have not been recently accessed/modified to "Online Only".

The feature also seems to tie the automatic space savings to placing new files into online only mode, which is counterintuitive. The best user experience typically requires new files to be in local mode for some time.

Files not accessed in xx days default to <local/online>.
