No! The writtenMorse project is not dead!
Yesterday I released version 0.3 of the Morse converter web app. This update brings better performance when converting large texts thanks to a new converting engine written in Dart.
You can test it now live at mmk2410.org/morseconverter.
Feel free to give me feedback either to me at opensource(at)mmk2410(dot)org or on the GitLab project. Thanks!
