Is there a way to view memory and/or CPU usage on an app/tweak/process basis? Either from the App Store or from Cydia. When googling, I only seem to find information for developers regarding how they can find memory leaks in their own apps... I assume this is something that a lot of people would be interested in, being able to see if a tweak or app is "worth it" or not. For instance, BatteryDoctorPro (from Cydia, search for it and you'll find it, its proper name is in Japanese I think) is a pretty interesting app, but it felt like the free RAM was disappearing for no good reason when it was installed. I would love to know if my suspicions are correct or not (I'd like them not to be ).
