Problem: when I read pdfs with more than one columns, I have to constantly scroll down each column, return to top, and continue scrolling. This is not only a hassle but also seeing other information in other columns usually distract me from the text I am reading.

proposed solution: It would be nice to have an option to scroll columns of text separately. For example the column that my mouse pointer is on it would become clear for reading and I could scroll it down, while the rest of the columns are slightly blurred to avoid distraction. By moving the pointer on another column, the scroll automatically would go to the top of that column and that column now becomes clear to read.

Thank you for your time.
