If you want, you could make a request to the chromium project for this feature.
Full window Notes Manager is now available in Vivaldi 3.1.
Check out the release blog here: https://vivaldi.com/blog/vivaldi-gets-notes-manager-and-configurable-menus/.
I moved this topic to the Done category and closed it since most of it is implemented already. Feel free to create a new feature request for the remaining feature. 🙂
Thanks everyone for your input and remember to post only one feature per request. 😉
