Tag Picker 1.3.0

• Search-and-pick window for adding tags to every selected item at once.
• Remove mode: pick from the tags on the selected items and take them off all of them. Switch with the buttons at the top, or Ctrl+R (Cmd+R on a Mac).
• Undo: every add or remove is one step in Zotero's own Edit › Undo (Ctrl+Z / Cmd+Z), with Redo.
• Tag colors: colored tags show their color and, optionally, come first in number-key order. They always keep their exact name.
• Tags come from your library, a text file, or both.
• Capitalization: lowercase, UPPERCASE, Title Case, or as typed.
• List sorted by how often each tag is used, or alphabetically.
• Keyboard shortcuts for Add (default Ctrl+Alt+T / Cmd+Option+T) and Remove (off by default), set by pressing the keys in Settings. "Add Tags…" and "Remove Tags…" are on the item right-click menu.
• A short confirmation appears after each change.
• Help window explaining every setting and key: the ? button or F1 in the picker, or "Tag Picker Help…" in Settings.
• Letter shortcuts are ignored while you're typing in a note or field.
• Works on Windows, macOS and Linux, and degrades gracefully if a future Zotero changes the menu, database or file-picker internals it relies on.
