Request

Thank you for the great tool, I love using csview and xsv together! Would it be possible to have csview behave more like a pager, namely to actually page the output when long, instead of having to manually pipe it again into less? Whilst I understand the complexity of having to introduce a pager within an application, do you think that can be considered in scope (perhaps in the future)?

Having to always pipe into less makes csview a little less independent as tool, as one would still have to use another application (less) to search and display results on terminal.
