Spell checking
Red wavy underlines with right-click suggestions, Add-to-Dictionary, and Ignore: full text for prose, comments & strings for code. Pure-Java Hunspell; English, Spanish, French.
Misspelled words get a red wavy underline; right-click for suggestions (click one to replace), Add to Dictionary, or Ignore. In source files only comments and string literals are checked (identifiers aren’t flagged); plaintext and Markdown are checked in full.
It’s powered by Apache Lucene’s pure-Java Hunspell engine, no native dependency. Ships English (en_US, en_GB), Spanish, and French; pick a dictionary per file with Spell Check: Set Language…, or set a default in Settings. Your added words live in dictionary.txt.
