ability to control automatic syncing

I should be able to start / stop the update daemon, so as to not waste PC resources when I don't want or need to sync.

 

In particular, since the files I backup are duplicated, I'd like to be able to delete the extra copy on my local drive without deleting the files backed up in the cloud.

 

(Note: this has been suggested in other postings, along with other features -- adding it as a single feature to better track kudos)
