Yes, Fan Control is still planned. We've had to pause this feature to focus on addressing bugs and compatibility issues ahead of the Big Sur release. It's still high up on my priorities for Q4.
The Clean/Uninstaller is getting a complete makeover, including background scanning, cached results and search functionality. However, it will probably not arrive until Jan/Feb. I know that may be disappointing, but there is just a lot going on right now with Big Sur release, SwiftUI changes, Apple Silicon Macs, etc, and I want to make sure these features hold top-notch quality and performance.
