Hi Gareth Day,
Currently, we do not have support for your requirements. Therefore, we have considered your request to ‘Provide option to show the line-numbers to content of the Rich Text Editor’ as an uncertain feature request from our end and this support will be included in any one of our upcoming releases.
Now you can track the status of the reported issue through the feedback below,
https://www.syncfusion.com/feedback/46950/provide-option-to-show-the-line-numbers-to-content-of-the-rich-text-editor
Generally, we will plan the feature implementation based on the customer request count, feature rank, and wishlist plan. You can upvote the feature request feedback so that it gets support and will be ranked higher for implementation.
Regards,
Vinothkumar
