Can you please consider moving the "Restart Required" From the toolbar? maybe put it on the status bar. You can make it really visible, change the color or whatever so the user still notices it - But having it in the toolbar is a an anti-usability feature.

Why "Restart Required" in the Toolbar is anti-Usability

Not everybody runs the browser to take up the full screen width. For example, I often have two side-by-side Vivaldi windows on my laptop screen, which means that I only have a usable five or six icons in the toolbar. So when this restart required appears in the toolbar, it means that most of my buttons are no longer usable because this message is so wide.

Furthermore, the most likely time that I will see this is actually at the start of a workday when I open Vivaldi for the first time. I will then see this thing and have to restart Vivaldi again, which is not my preference.

My preference would be to notice that I need to restart with Aldi at some time, but actually wait until I have a little bit more free time to do it. That's why it would be more effective in the status bar. When it sits in the toolbar and blocks most of my buttons, that's all I can think about, then I can't click those buttons. So I don't really have much choice but to restart Vivaldi again. And I know this sounds like a a relatively minor thing, But it's just another thing to do when you're just trying to start your work day.

Or another alternative to putting the status bar would be to put it like in caps or something, in brackets in the in the title bar of Vivaldi.
