1.13.0

Navigator row quick actions. Props to TRẦN ĐỨC LƯƠNG (@evanscliff) for the suggestion.

• New: Duplicate and Delete buttons appear on the Navigator row under your pointer or keyboard focus (Navigator tab, on by default), with full keyboard and screen-reader support — from a focused row, Tab reaches the buttons and Escape returns.
• Focus follows the action: to the copy after duplicating, to a neighbouring row after deleting.
• Delete asks for a confirming second press (the button turns solid red and renames to "Confirm delete") and remains undoable with Ctrl/Cmd+Z while Undo delete is on.
• A sub-setting can pin the buttons to the selected row instead of showing them on hover.
• Fixed: in the light theme, an element's display-conditions view (the settings panel's conditions mode) rendered dark-on-dark — the "New condition" button, the condition cards, the separators, the date/time fields, and the comparison, value and multi-value pickers all kept their native dark surfaces. All now follow the light theme; dark is unchanged. Props to Tim Gray (@snipkin) for the report.
• New: Display-condition helpers (Editing tab, on by default) — opens a blank, ready-to-choose condition when an element has none yet (removed again if you leave without touching it), gives every condition field a proper screen-reader label, and marks elements that carry conditions: a dot and count on the conditions button, and a dot on their Navigator rows that screen readers announce.
• Improved: the multi-value condition pickers are now keyboard-operable — the picker is focusable and announces itself, Enter or the arrows open it, Space ticks a value, and Escape closes and returns.
• Fixed: the dynamic data picker (the stack-icon pop-up, shared with the CSS vars and transformation-function lists) rendered black-on-black in the light theme wherever it appeared — including its hovered and keyboard-focused items; it now follows the theme, dark unchanged. Its controls also gained the visible focus ring they were missing in both themes.
