Organize your Dock
Click the + slot at the bottom of the Dock and choose New Group… to name a group and pick which Pickles go in.
Drag a Pickle onto a group and it moves in when you release. An empty group shows “Drop a Pickle here”.
Press and hold a Pickle in the Dock for about 1.2 seconds to archive it. A toast appears at the bottom right; click Undo within 6 seconds to bring it back.
