Having tools to make it quicker to bold text, add tables, create links etc. rather than having to know the html.
We use a product called CK Editor https://ckeditor.com/ for our internal systems and it works well and is easy to implement from a coding perspective.
I'm guessing it hasn't already been added due to subscription fee costs with yours been a commercial product that you are charging a fee for but could be wrong.
I have added a few example images. I know you can choose which buttons to add.
It would be good to have these tools as part of the content/ department/ product editor, as a solution in the meantime I format the text in word and copy it into this html formatter, https://wordhtml.com/
It saves a bit of time!
