In Spring '17 they introduced Quill to one section of Lightning - Notes. You will see at the moment (Spring '17) that Rich Text Editors do not work in Sandbox because Locker Service is enabled by default. Quill is apparently built by ex Salesforce people, and is one of the only editors that works with the new security settings. Basically, due to some security issues (part of Lightning Locker Service), all the Rich Text Editors need to be replaced. QuillJS is the new Rich Text Editor for Salsesforce. So have to ask them to create it in Knowledge, or an external editor, and then paste it into the HTML Editor for the custom field. But there is NO WAY for them to create this HTML in the Rich Text field. They want their emails to look nice, so the Rich Text field needs to have the EXACTLY formatted HTML that will display on the emails, and fit the Corporate Style Guide. To allow for users to have control over their email templates that are sent out to Campaign Members, I create a basic Visualforce email template, that references a custom Rich Text field on the Campaign, where they can add all the details of the Event on the Campaign. NO HTML LINKS! How is that even possible? But there are images! New Quill JS Editor in Notes in Lightning Spring '17 - oh we have just gone so backwards.Again, font and size should be a corporate style thing - AND THERE IS NO WAY TO INSERT AN IMAGE! New Lightning Email Editor - just to make things completely different again.HTML Email Editor - old and ugly, but still has some basic formatting functions like Font and Size.

If this one were everywhere, I could just about cope with that. Knowledge Article Editor - good enough text formatting, and View Source.(This is where you DON'T what users to be adding all sorts of colours and fonts - all formatting should be controlled through the HTML Email templates to maintain a corporate style). Case Feeds HTML Editor - Font, Size, Format and colour, no View Source.

Standard HTML Editor for Rich Text Fields no text formatting functionality, No View Source.
