I'm writing this post in the newest version of my Quill editor, which I hacked together at IndieWebCamp Germany. I was inspired by Glenn Jones' nice editing UI for Transmat (now separated out as a separate component and published here), and wanted to create something myself that was more than just a Bootstrap form.
Below is what the editor interface looks like. It's heavily inspired by Medium's clean editing UI. It also supports AppCache and LocalStorage so that drafts are autosaved, and the app loads quickly and works offline.
I'm looking forward to having a nicer interface to editing my posts than writing a markdown file in a text editor, which was my previous workflow!
