Hello, As a long-time user of Okular PDF viewer, I have come to appreciate its features and capabilities. However, I have a suggestion that I believe would improve the software even further. Currently, when I use the underline tool in Okular, the corresponding annotation appears in the sidebar under the title "Underline". I would love to be able to rename this title to something more descriptive, so that I can easily search through my notes and find the information I need. Thank you for your time and attention.
The PDF specification doesn't have a "name" field for annotations, so we can't let you change the title because there's nowhere to store that new title you would use.
