Hi Adam, thanks for the compliment and your feedback.
We are able to kill tasks automatically to free up some RAM, but they usually start themselves right back up and continue running in the background.
Android doesn't provide an API for app stopping, so you have to be looking at the app while behind the screen we "manually" open app settings and tap "Force Stop" for you. If we didn't display this "app stopping progress" overlay screen, you would see your Android settings opening and closing. We wouldn't want to start this process automatically and interrupt what you're doing. We also can't perform this process while your screen is off.
I don't think we'd add much value by killing tasks automatically for you, and it's not possible to stop apps in the background. You'll just need to tap the permanent notification when the count gets high and tap Stop Apps.
I hope that helps.
