Two-column articles are quite common, especially in academic fields. Two-column is great for reading when you print things out, but a lot of pain for reading on the screen, since you have to scroll across a page over and over again. Is it possible to add a view mode suitable for two-column?
This may be done by
- Zoom fits half-width of the page
- Whenever hitting the bottom of the left half of a page,
jump to the top of the right half of the same page.
Since there are articles whose left and right margins are not the same, it may be better to identify the white space between two columns and let zoom fits the wider column. But I understand this is not a trivial task. So rather than a complete zoom + scroll mode, a single scroll mode that repeat a page once, will also be greatly helpful for reading two-column articles.
For example, when viewing a page for the first time, align to the left of the page. When scroll hitting bottom,
jump back to the top of the same page, and align to the right. The second time hitting bottom, scroll down to next page as usual. Such scroll behavior together with a customized zoom will suffice for reading two-column articles.
