Hi everybody,
I wrote an e-mail to Foxit Support asking them if the eSlick supports 2 column PDF files. I attached one of my research papers to the e-mail. This is what they sent me back (check attachment). Quite decent. Except that the reflow feature (second picture) doesn't handle spaces between words that well (I wonder why, it should be easy enough to fix).
