I added an advanced editor to #imwald. I'm testing it, locally, and it seems like some sort of miracle. CodeMirror for Markdown and Asciidoc, grammar and spelling checks for all languages with my own instance of https://languagetool.org/, translations with LibreTranslate that can handle markup, citation event helper, Latex helper, custom emoji support, undo button, local autosave and recovery, npub/naddr/nevent mention, etc.
