I will do my best to word this...
Currently if you change the name of a column in AppSheet, there is a high probability of breaking the app because the name of the column is likely used in other places (automation, webhooks, etc)
AppSheet is aware of the issue, as it gives you error notifications to go to the problem.
Stands to reason that AppSheet could/should automatically find all references of ColumnNameSteve that has changed to ColumnNameBen, and update those named references to the column (not reference in the Ref sense of the word, mind you) to reflect the new name.
This would save the end user from clicking "Go To The Problem" and changing the fields shown on forms, re-typing JSON for webhooks, etc.
