Three from UAT: the row's cap goes 1280 -> 1472 (+15%), since with the
rail and filters hidden there was a lot of page left over and the fixed
columns mean the extra width can only go to the title; the views column
drops the word and keeps it in the tooltip (a table doesn't repeat its
unit every line), taking that column 144 -> 64; and the view switcher
names the current mode where the toolbar has room, falling back to the
icon alone below xl. Title: 431 -> 511 at 1440, 706 at 1900.
