No good, easy to use highlighting tools available.
As a user I want to quickly underline or highlight some text. That currently is painful (or I have not figured out how to do this, in that case it is not intuitive). I dont want to go into editing mode with the risk of editing every single element on the page, accidently move the text block etc. Just want to use my pen to quickly select and edit a chunk of text.
See Foxit Mobile (they have done a great job, also with dark mode) however, the project is discontinued.
