v1.2.0

Two picker fixes that make ^S behave — and make the picker teach itself.

^S on a running session opens a terminal there. Since 1.0.0 the picker's cursor boots on the first running session, and ^S on such a row silently jumped instead of creating anything — "new session → ^S" hopped to a different session on every try. ^S now means "terminal session at this row's directory" on every row; Enter still jumps back in.

The picker explains itself. The bottom hint follows the cursor and says what Enter/^S will do to that row (jump · terminal there · resume). The ? cheatsheet says keys act on the ▸ row and gains the missing ^T line; both READMEs now spell out that picker keys are pressed inside the popup — no prefix needed.

Upgrade: pier upgrade (or brew upgrade zkzofn/tap/pier).
