Agreed that showing the gateway here would be nice. We probably want this change in the Subscriptions tab as well, along with including the Subscription Transaction ID there.

Long-term, it would be nice to have a system for showing/hiding individual columns similar to the "Screen Options" dropdown on List Tables

Thanks @dparker1005 I have committed those changes, good catch. I'll do a PR shortly for Subscriptions tab (in a separate PR)

I approve of this - we should be cautious since there is less horizontal space on this panel and also since admins cannot change visible columns. We can tackle some way to have columns hidden or shown if we feel this gets to a place where there are too many columns. For now, we have the space and nothing is wrapping too much even on my Macbook.
