Great developer, excellent communication and support. Unfortunately, as mentioned below, the developer has decided to sell through the Mac App Store exclusively. Selling through MAS brings the developer benefits such as more sales and less work maintaining a registration scheme but really hurts the product and in turn end users. The original Lingon was much more powerful but has been abandoned and removed from MAS. Lingon 3 is a nice app but due to MAS limitations of letting the app access the entire file system users are restricted to creating/editing LaunchAgents in their own ~/Library/LaunchAgents folder instead of being able to visually see and edit items in more critical areas such as their root launchagents and launchdaemons besides all the system agents and daemons. Fortunately, if you were lucky enough to purchase Lingon before it was removed from MAS it still works great on Mountain Lion but the fact that we have to use "dumbed" down software or software that is half as powerful simply because it is only available through MAS doesn't make sense to me. Developers can't offer extremely powerful software, thanks to Apple, simply because indie developers need/want more sales and the publicity that MAS offers.
However, I don't see the point in not offering a version available through MAS and a version available straight from the developer that is not crippled to meet submission guidelines. Developers, you still get MAS publicity but your customers that need more out of your software are not left out. I love Peter Borg's software and his customer service but, unfortunately, I can't advise anyone to buy this software. Give your users full software, I don't care if you charge more because you have to deal with an online merchant and licensing company, we understand those costs and will gladly pay them.
Final thought on rant, customers, don't support devs who only sell on MAS and deny you all the features you could have in an app but rather show them that offering a non-mas version of their app pays by supporting the developers that make powerful apps with demos that are sold directly by the developer. Just don't buy MAS apps and let this nonsense be the way of the future. I think it comes down to us, end users banding together. The only way we can influence, I hesitate to say force, developers to make non-mas versions of their software is if we show solidarity and no longer support/buy their apps if they are only available through MAS. Nothing drives the message home like a hit to the wallet so don't buy this app, your better off compiling an old open source version of the original Lingon. The GUI may not be as pretty but it's more user friendly and powerful. I will find a copy of the last open source lingon version and post a link here so you all can compile it. I'll post a link in a bit to a compiled version and the actual source.
