This document describes how to use Filter 2 in Filterize to visualize notes with emojis. It provides three examples: 1) Visualize notes by tags by adding emojis to denote tags like contacts or categories. 2) Visualize the source of notes by adding emojis to denote sources like notes from the web clipper. 3) Visualize to-dos by adding emojis like checkmarks, squares, or exclamation points to denote the status of reminders as open, overdue, or complete. It explains how to set up the necessary filters for each example to automatically apply the emoji visualization.
