I hesitate to make suggestions here, because of how even the most popular and basic requests have yet to be implemented, but I will anyway.
I would like to be able to execute an HTTP request against values in other fields. This is possible in Excel and would be just as valuable here.
The most basic implementation would use the GET method where I would define the URL and querystring separately.
Yes, this would be an advanced feature that would generate support requests. Perhaps it could be hidden behind an Advanced Features toggle in a workspace’s or base’s settings.
