~6 years ago had a very hard time researching and implementing an @-style remote resource completion (other users and documents to reference) and the style of extensions in this editor seem very much like an evolution of prosemirror.

I'd really appreciate it this was something built in, not something I have to build based on the dinosaurs example. Every time I need to reach for one of these text editor libraries that is my no. 1 usecase, followed by WYSIWYG.
