Also, please give us a separate forum and separate help pages because many Android tips don't work in ChromeOS.

It installs from the Android Playstore, as do most Android apps, with a "desktop customised" version. Better than Chrome in several ways, especially privacy - separate password vault, cookies reliably deleted, etc. However, we could do with a separate help page because many tweaks for Android simply don't work in ChromeOS.
In particular, I'd like to hide the side menu bar for more screen space .Opera say "Alt F11" but there are no F-keys on a Chromebook!

We need a way to discuss this separately, please!
I found a 2020 closed thread in "Windows" about it, in which someone said they didn't think anything but Chrome is possible on a Chromebook but, even then you could install Most Android apps. Also, Opera have their own webpage saying the Chromebook version is specially formatted "with laptop features". However, there doesn't seem to be a special Help Page and many tweaks suggested under Android simply don't work, nor those for Windows, Linux and iOS.
Specifically, I'd like to be able to edit my speed dial and to hide the menu bar.
