I have other suggestion. While stop? Let's delete ALL borders and colors, just white list and 2-pt light-gray color text. It's so cool, designers like this IPhone-style.
For serious, where are people with low vision eyes. And on 22+ monitors gray text has low contrast on white page. I see this on many sites. And wait while IPhone will change design and sites too ))

I use extensions like Vertical Tabs or V7 Tabs, and after updage from 64.0.3417.92 to 67.0.3575.79 it's behavior goes unusable. Because then I click on tab, panel hides and I see no tabs. I must click extension icon on left panel and select other tab. It's not good. How to pin panel? Where is any start option for this? In flags don't see anything.
It's not difficult for developers write something like:

if ($start_options[x]=="--start_with_pinned_panel") then $panel_autohide=off; fi

Do it please. Or say while it's imposible.

Please Add this! It's was killing-feature of Opera and Firefox for me. But Firefox for Linux is die since going from Alsa to Pulseaudio. Vivaldi starts 7 minutes with 300-400 tabs (it loads tab, then suspend, one by one o_O). Only your browser can make people happy
