DROPBOX warning.
Dropbox is back in PP2 - however, it's implementation is dangerous. It syncs your entire Dropbox account by default. To exclude folders, you must type each one in by name - not practical if you have hundreds of folders as I do. OK, it says you can delete the folder from the Controller to stop further syncing - BUT what they don't tell you is that by doing that you delete the folder from your master Dropbox account too. So it won't sync because the folder no longer exists, anywhere.
