A quick suggestion:
We now use quite a lot of international tax IDs, and it's quite confusing to figure out what's what on the setting page: https://ship8.shipstation.com/settings/international
There doesn't seem to be any logic to the order the IDs sort in, and I'm wondering if it would be possible to add a function to sort the columns by any of the headings, which would make it a lot clearer.
Thanks
