It's been a little while since we've heard from St. Clair Software, makers of the well-known system utility, Default Folder X (which we've covered before). You may recall that we caught up with St. Clair Software developer Jon Gotow at WWDC '09. Well, he's got something new to announce today: App Tamer, a system utility for keeping CPU-intensive applications under control.
App Tamer is similar to some other utilities, in that it allows you to "freeze" selected applications so that they use up zero CPU time, leaving more processing power for other applications. What makes App Tamer special is AutoStop, which pauses and unpauses frozen applications when you switch away from or back to them. It also has options for temporarily unfreezing applications at a configurable interval, allowing apps to complete background activities even while frozen. It's quite flexible, but takes very little user knowledge or time to get it up and running.
