[Feature Request] Add a "copy" button on the internal notes section

I work as a chat/email support for Secretlab. When we handle tickets, we always copy the notes, and paste it, and add more notes to it per ticket, and it's tiresome and inconvenient because the notes are very long, so we will need to highlight the text from top to bottom or vice versa while scrolling down or up the page at the same time. It would be great if there's a COPY button in the upper-right corner of the note so that just by clicking that button, the note will be copied instantly and immediately, so we can use the copied note again easily and paste it and improve it. This is very useful on every ticket we handle, especially those which have long threads.
