I love the Tab Center idea, it is a much needed usability imporvement for small screens (like almost every single work laptop in the last 3 years).
One feature I like is the favicon view when the tab center is resized to the minimum width. However manual resizing makes it stop the automatic expansion on mouseover. This way tab search and tab titles are not accessible.
I believe it would be very nice to have the option to have an expandable favicon view as standard tab center interface.
