I’d love to see a warning before allowing a change such as a Field Type that might be destroying data.
I just created a new field. In the process of scrolling back and forth between the last field in the database where the new field appeared, and then creating a new record to see if the default value was working as desired, I inadvertently change the field type of the first field of the db destroying that data without any warning. I then Saved before realizing my error.
Then I found that Revert To… Browse all Versions was crashing and not working at all. Now I am attempting to revert to a backup that will not have recent data.
A warning that a change will destroy data of some sort may have saved a lot of time.
