I would like to have an app (that runs on the desktop, not a phone app - text would be too small) that would allow me to simultaneously have both the Spanish and the English versions of material displayed side-by-side.
Specifically, I want to read Don Quixote that way; but actually, I would like to be able to load any pair of documents in that way. IOW, it'd be nice to be able to download the Spanish html and the English html (or text files) and load them up in this utility.
The optimum would be if scrolling down in one of the panes simultaneously caused the other pane to scroll down with it, but would also allow independent scrolling for those cases where one or the other panes passages was longer.
IOW, I guess a "global" scrolling action to scroll them together as well as an independent scrolling action for each of the two panes. Is there such a utility available?
