This is absolutely imperative for best-in-class component management. Great idea, Adam.

This is possible currently, though it's not immediately obvious and could be a lot better. Just right click on a column and choose "Add time period column". Then you can manually ensure that the two columns are included in your trend visualization.It sure would be nice, though, to just be able to add something like this to a line chart without adding it to the table. And to have it normalized and automatically updated.

Absolutely agree with this. Google Analytics has had regex since the beginning, and it makes filtering results very powerful and very easy.
