Rated 3 out of 5 stars
I really like that this add-on is lightweight and allows you to select the specific element to apply it to. Of course, as others have said, it could really use a better/more user-friendly user interface, and perhaps that is where my problem comes in.
I cannot for the life of me figure out how to disable that fade effect on the top and bottom margins. It's making certain lines of text unreadable, which defeats the purpose of an add-on like this. Example: https://www.dropbox.com/s/cugomsmthwms6cf/Capture.PNG?dl=0
How do I get rid of that fade effect? It needs to be gone.
Column Reader is content-agnostic, so it cannot correct for lines that are cut in half - the fade out merely keeps these lines readable and makes clear where to start reading at the top of the column. I guess it takes some time to get used to.
In the future, I might create an extension that makes use of CSS columns, which do have content-aware layout. However, CSS columns did not exist yet when I developed Column Reader.
