Simple yet excellent menubar app for managing SSH configuration. I've had no problem editing my ~/.ssh/config files using the command line (with VIM), but for a couple of dollars this GUI just makes it that much simpler. It saves me time, and time is money. It's saved me way more than $3. So, I think the price is very reasonable. (I was happily using the free version, as developer only switched to having a price on it very recently. I've happily paid for it on App Store, even through I was pretty much on the latest version. To me it's a no-brainer to keep the developer fed).
It could do with a few additional features, such as Duplicating previous entries. Developer was very quick to respond when I sent him that suggestion, and says he'll make a quick host config option in a future release. Nice.
