I enjoyed that brief Android Chrome experiment where the browser supported moving the address bar to the bottom. Now that feature has been made available on iOS, but remains AWOL on Android.
Why do u still use chrome? I suggest switching to Thorium, Vivaldi, Firefox or Kiwi. Edit: all of my suggested browsers except Thorium(at least I didn't find it, plus it's a relatively young browser) has bottom toolbar. Same dev is working on lighter Firefox version called Mercury, it's not on phones yet.
