I think it would be useful to have a feature that would obscure private data in the data editor.
What I envisage is a per-column setting (similar to ‘Mark as Protected’), where you can tag a column as ‘Private’, and this would have the effect of obscuring all data in that column. ie. It would be displayed as *******
(or similar). The difference between this and the existing Mark as Protected feature is that the data would still be accessible.
I would see this as a security enhancement, and would help avoid the situation where private data is accidentally shared via screen captures or videos.
I’ve not created a feature request, but will do if there is support for the idea.
