Adding Bookmark button in notes

[sagarb2003]

Users can mark their favorite notes by clicking on a bookmark button. When they want to see these saved notes later, they can find them in the bookmark section of the website's menu, but only if they've logged into their account. If someone tries to mark a note as a favorite without logging in, they'll be asked to log in first through a pop-up message
