Describe the feature request:

I've seen a lot of discussion about the new tab bar. I've had a couple of issues using it and it's been my main pain point coming across from Chromium. I thought of one thing which might fulfill the intention of the new tab system but address some of the issues (e.g. #879).

We could allow the user to set a minimum tab width (also discussed in #6692). This way, for small or large screens the user experience with 'many tabs' will be the same, and will be the way the user desires it. For users who are okay with only favicons the min width could be Icon, for users who want at least the first 1 or 2 words they can set a 'short' width (possibly the default?) and there could be another one which shows the first 10 whitespace-separated words of each tab.

Tab set behaviour would move to the next set if the calculated total width would exceed either screen width or some other computed value (e.g. width*2). You could also have the number of tabs option as an alternative or complementary option for users to select.
