I’ve been using Brave a lot lately and I enjoy but as a personal opinion, I think the User Interface (UI) is a little bit condensed.
1 - The Tab size is kinda small
2 - The Tab font size is kinda small
3 - The Address Bar is on the smaller side
4 - There is not space between the Tab and the Window itself
It’s only personal opinion but I think for older people especially, this should be improved.
As a personal thing, I kinda enjoy Edge interface. It has big tabs sizes, the font is is bigger and easy to read etc.
The following flags settings are useful for controlling the tab size, size of address bar and width of screen width. Open brave://flags/ and enable the flags:
tab scrolling
Touch UI layout
Overlay scrollbars
As for the font size you can controlling it by going to Windows Settings, Accessibility.
