Users seem to really like being able to customize entity tables in any context, to create something specific and useful in different places.

There are two places where I have discovered one cannot save a the reconfigured table (columns, filters)

from the My Entities component on the homepage

from the view entities button on a blueprint on in the data model view

I'd say the former is bad for users. We shouldn't offer anything on the homepage that can't be tidied and saved

I'd say the latter is bad for builders/power users, who delete catalog pages, but still want/need to browse entities for a blueprint from time to time
