Add a setting to create / edit entities in a modal (submodule?)

Problem/Motivation

First of all thank you very very much for this great module! I saw it in Drupal CMS and it works like a charm. :)

One thing I think would be a really great addition in the functionality, maybe as submodule, would be to have a widget functionality (and setting) to allow editing or creating (more complex) referenced entities in a modal.

Simple tags, where only the label is needed for auto-creation can already be created automatically (but can't be edited). For more complex referenced entities, the label might not be enough, but still Tagify would be a great widget.
So it would be a great feature to have create / edit functionality in a modal as future feature! Having that in Tagify and thereby Drupal CMS, the overall functionality in Drupal would benefit a lot!

What do you think?
