Yes, indeed: the first thing you should do is explain what you are
trying to do. E.g. what does "est+" mean? Once you have explained
*what* you are trying to do, then somebody might be able to suggest
*how* to do it better (if it is a worthwhile thing to do in the first
place).
I'm not sure I understand your question. est+ is an existing functionality
in columnview that is documented. I've brought it closer to the regular
effort functionality by supporting time units.
