Add Highlighting and Sticky Notes Feature for Lessons

While going through a lesson on Uxcel, I found myself wanting to highlight key lines to help me focus on the most important points. It would be incredibly helpful if there were a feature allowing users to highlight text within the lessons, just like we do with physical books. Additionally, being able to add sticky notes or quick annotations next to specific lines or paragraphs would enhance the learning experience, especially for jotting down personal insights or reminders. These features would make it easier to review and retain information more effectively.
