DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.
Menus can drop the number column, and the vim indicator no longer crowds the hint

Terminal UI
Menus can hide the number beside each option, and vim mode no longer crowds the input hint line.
What's wrong with this entry?
Anonymous. No account, no email.
What
Selection menus can now be rendered without the numeric shortcut beside each option, and the input footer suppresses its dense hint text when the vim mode indicator is showing, so the two no longer fight for the same line.
Details
The menu behaviour is chosen per menu, not by a setting or flag.
Evidence

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
