I believe you’re right. However, if memory serves, the ads did change occasionally, meaning the screen had to refresh, leading to increased battery usage.

I just sent them a message asking them to disable the ads on the kindle I had recently purchased, and they did so for free, no root needed. That was a few years ago though, so I doubt they do that anymore…

I find that Neo covers most of my needs. Although there is one thing in particular that I miss: swiping actions on seperate icons to launch another app/action. I haven’t used Nova in a while, but it had nicer previews inside the options, and I find that Neo has a few minor bugs that annoy me at times. But Neo has the things that are most important to me: multiple pages, tabs or folders in the app drawer, icon pack support, search and gestures (not on each icon, as noted earlier). I also miss the ability to place icons between the defined grid as in Nova.

I stopped using Nova Launcher when it was aquired by an analytics company, since launchers usually have access to a lot of permissions, and I don’t trust a company dealing in analytics to operate in good faith with that access. I have used Lawnchair 2 and recently switched over to Neo Launcher.
