Go foss to avoid further enshittification.

Try Octopi Launcher. The menus are different, but you can customize I'd say 85-90% identical to anything you could do in Nova. I duplicated my entire setup and it feels 90% the same.

Smart launcher will let you import your nova backup and transition seamlessly. That's my recommendation.

I hate this suggestion but it is the only one I've been able to stomach as something that operates like Nova: Microsoft Launcher

Its actually quite decent and mostly seems to be a forgotten piece of software so it hasn't been enshitified.
