What are the best J-J dictionaries for Yomitan or otherwise available in text files or online that specifically nuance 類義語 or different Kanji spellings?

I already have 大辞泉, 大辞林、使い方のわかる, and 類語辞典 from the usual Dropbox source and check goo辞典 myself. Are there any others that can complement/supplement these? I’m looking for detailed clarifications on word sets like 識別 vs. 判別 vs. 区別. The more detail and elaboration the better!
