Is there now, without feature-requests, a way to set migrated posts as categories to hide or display? If there is no direct feature, can it be done by
adding a tag like migrated-to-mse to questions moved to MSE from other sites, or migrated-to-meta.mse for things that land on the meta site?
This would allow a user to Ignore things that are out-migrated when reading the originating site, and to handle migrated material in searches.
[migrated]
at the end of the title. $\endgroup$is:question migrated:no
it will return all questions which have not been migrated away from the current site. I am unaware of any simpler way of filtering out questions which have been migrated. $\endgroup$
