Is was wondering if it would be possible to implement something like a Global Pause-Button. At the moment it is possible to pause syncing for single Folders. The motivation behind this request is, that I sometimes tether my notebook with my phone an I don't want owncloud to sync during this time.

I know that I also could quit owncloud and restart it when I'm back on a "normal" connection, but having such a pause option would be quite handy. Maybe this Global Pause-Option could be configurable, like:

Pause for: 10min, 15min, 30min ... "resume manually"

Edit (@danimo): The implementation should also contain a possiblity to pause/unpause from the command line as to hook it up to scripts, see #2760.
