@MilesV64, glad you're finding Proton helpful. For your case of inserting text at a given range, you should be able to use replaceCharacters. You can prepare your content i.e. attachment with required spaces on either side and use replaceCharacters to append that to the Editor at given range/selectedRange. Attachment also has a string property that you can use to get an NSAttributedString representation that you can use to append spaces easily. In regards to the attributes, you can look at editor.typingAttributes and add that to your prepared string. In summary:

• Create a mutable attributedString with space as starting character, if applicable.
• Append attachment.string
• Append trailing space
• Add typingAttributes from the editor to the entire string
• Use replaceCharacters to add the attachment/spaces to Editor.

In regards to RichTextView, it is not exposed as there are some constructs that are required for Proton to work which, if RichTextView is public, may get accidentally overriden by consumers causing unexpected results. Exposing some bits may still be possible but I think we need to discuss that as a separate issue.

For intercepting content changes, you may want to look at TextProcessors that does provide content related callbacks including that for insert/delete text, which may also be an attachment
