I was searching through Safari extensions looking for something that would extend the MacRumours (and others) site to automatically fit to my current screen width (I simply use Command +) but alas didn't find anything. Anyway I did com across a really handy extension that can add tasks to Synologys download station. I've not had a chance to review it fully but my initial impression is very good. Seems it's also can download YouTube videos. Worth a look for any Synology NAS owner. It can be found under the "Productivity" section.
