Now that we have native terminal support, it would be a reasonable project to write a pager in Julia. Why write our own pager (you ask)? Because it could allow you to do things like efficiently page around a huge array without having to print the whole thing. You could, e.g., instantly page to the bottom right of a massive, distributed array, without any lag at all. Of course, the thing is you want to use shared infrastructure for doing this kind of data exploration in the terminal, IJulia, and maybe your editor. But the pager part could be pretty decoupled from that.
