Chordsheet maker online is not complete yet and there are some known issues.
But it is already usable and I use it myself. So I regularly improve the site, fix bugs and add more features.
If you are curious what is new or want to observe the progress have a look at the changelog occasionally.
New features to come might be already on the roadmap but don't hesitate to send any ideas and suggestions by email or use the contact form.
Stay tuned and enjoy the music.
