Actually, you can click through.

In the home page, go to settings -> Advanced settings -> [X] Click through mode.

Yeah, I know, some settings seems really hidden.

Besides the floating button, the side bars have more gestures (like swipe left + swipe down, for example) and it can perform more actions.

Totally agree. But, unfortunately, the only other option I found is coolapk, an all chinese website.

Tô pra descobrir ainda kkkkk

Me using it: https://imgchest.com/p/ne7blavny53

• App Manager - An app manager with super powers! With this app I can keep track off my apps permissions, operations, launch activities, freeze or uninstall bloatware. Although, my main reason to use this is the built-in apk/apks installer that shows the components, trackers, and differences between versions when updating an app. It has even more features I can’t say. Truly amazing.
• Aves - Best gallery app on Android. I love the mosaic view!
• KDE Connect - Connect your Android with you PC. Can share files, sync clipboard, control media etc.
• RethinkDNS - Best DNS/Firewall app I’ve ever used. Doesn’t consume lot battery and it’s super configurable.
• URLCheck - I can’t live without it. With this app I can check, modify, unshorten and remove tracking elements from links, and even select the app you want to open that link with - Really nice when using work profile.
