I'm still a beginner learner, so I normally don't bother looking at the C-C dictionaries, but once I happened to look at one of the 注意 notes in the GF dictionary, and I was blown away! It explained things like when to use different pronunciations of the character and other stuff that was useful to a beginner like me. Are there any C-E dictionaries with similar notes? Yes, I know that the OSC/OTC have interesting notes about the characters, but I'm looking for notes about usage and pronunciation.
