I use plenty of extensions and find that I can’t read usefully the address a page is on. This is because there is unused space before and after the address box:
the gray, empty space above the two black bars I’ve added. Chrome doesn’t waste this space.
It’s often important to see the actual address.
I can see more if I make the browser window really wide, but this shouldn’t be necessary. In the example shown, the browser window was 1252 pixels - not unusually small.
Yes, why is the default not to expand it? What’s the idea behind it? Was that just a chromium thing you didn’t bother to change and yet you added a setting for it (or is that setting also a chromium thing)?
I’d love to know for curiosity’s sake. It’s a really weird thing to do…
