I just pushed a fix that expands the preference to three options:
- Show confirmation when marking feeds or folders as read
- Show confirmation only when marking folders as read
- Mark as read without confirmation
This now covers all forms of marking as read: the button, the time-based options (1d, 3d, 7d, 14d), and the Shift+A keyboard shortcut. The confirmation itself is now an inline prompt in the feedbar rather than a full modal.
This is now deployed.
