Text editor with inline English-German dictionary▲35
Hi When you are learning a new language, you need to practice different skills: reading, listening, speaking, writing. I find writing to be the hardest activity, not least because I have to look up words in the dictionary all the time, and that is a frustrating context switch. Here is an experimental CodeMirror-based editor, that lets you look up translations inline. Type @ followed by the English word, and get a list of possible translations, and select the translation to apply it. Online demo: https://foreign-dispatch-autocomplete.netlify.app/
