We definitely plan to take a pass at the web layouts where we have a lot more real estate (potentially) and that makes sense why columns would help. Flexible layouts are challenging but indeed offer differing display options when the real estate permits. We'll take a peek and see what we can do.
Regarding the device data export, that one is also on our feature request list. Thanks for affirming the idea. We try to pull in a few requests with each new release so stay tuned.
