Tools to learn to distinguish multiple radical patterns

There’s a large portion of kanji that fall in the Semantic-Phonetic Component kind of kanji (one kanji in charge of the meaning of the compound and the other part accounts for the reading).
For those the Keisei Phonetic-Semantic component script is one of the best tools. You’ll see kanji sharing the same phonetic component, and that can really make wonders as to classify them into something more digestable.
