I move around from the office and elsewhere quite a lot. When I'm in the office, I need a static IP, elsewhere I don't. I have network locations set up, but it's extremely tedious opening up Network Preferences to change it essentially every day.
Ideally I'd like an app where I can just select from the taskbar menu, like I can with Wireless networks, or a way to apply the IP config whenever I connect to that specific network.
I've found paying apps, like Sidekick, which are massive overkill (I don't want to shell out £20 for an app I'll only use one function of), I just want a tiny utility. Is there such a thing?
