The connection sometimes is interrupted, and reconnecting manually doesn't work. This is quite serious.
I've been waiting for something to come along to replace the old (but useful) SSH Tunnel Manager (by tynsoe.org). This is finally it! My biggest pet peeve with STM was that is didn't start on load and didn't run in the background (it was always in my app switcher). This app seems to have all the same functionality with the nice extras. Thanks!
