Comparing "xiangfa" and "zhuyi"

想法 (xiǎngfǎ) and 注意 (zhǔyi) are both nouns that are often translated as "idea." 想法 is used more in informal settings, whereas 注意 is used in both informal and formal settings. 想法 is more of a thought or opinion, whereas 注意 is the classic "idea" (think "good idea!" as in a response to a plan that someone else proposes).
