Responsive column size for chui-ui

[lucywang000]

It's common to have the editor and the browser (with the test tab open) positioned side-by-side on the screen. But the current chui-ui is not responsive, e.g. what about when the browser viewport width is small, it just hides the list of test runs, since most of the time people only care about the last run. Or it could provide a button to manually hide a column.

Would you say the new resizable columns alleviates this somewhat? Obviously it's not fully responsive, but I guess the majority use case is when you have it open in two browser windows like you said, which I guess it helps for?
