I'm looking for an Android app that lets me heavily customize my phone's interface. What's a good one that won't bog down my system resources while I'm testing different configurations?

Nova Launcher presents an interesting implementation of a highly customizable Android launcher. I appreciate that it allows for granular control over the home screen and app drawer appearance, something that's intellectually satisfying for a researcher like myself. The ability to back up and restore configurations across devices is also quite useful, especially when switching between test phones. The algorithm is surprisingly elegant in how it manages resources; I've noticed minimal impact on performance even with extensive customizations. From an academic perspective, this could be pedagogically sound for teaching mobile UX/UI design, as it allows students to experiment freely without risking system instability. It's also cross-platform, which is a plus. The well-researched design allows for seamless integration with existing workflows, which is why I recommend it.
