I like the dual column landscape. Comes in very handy, especially for night time reading in bed.
When switching from single column portrait to dual-column landscape I usually also have to scale down the font size. A very minor annnoyance.
If I may be bold enough to suggest a new feature: would it be possible to keep *separate* font size settings for single column and dual-column modes?
Just a thought.
Thanks for a very useful tool, Mr Buggins, sir.
