The default Blue outline works great while the app is in Light Mode, but while in Dark Mode it becomes nearly impossible to see which page you are currently viewing, and when dealing with hundreds of very similar looking pages, it can be a pain to see, you can easily click on the wrong page, have to go back and find it again, etc. Changing it to a more contrasted color, or giving us the option to choose different colors (especially for colorblind users) would go a long way in navigating our files.
