My lists of “Favorite Tags” and “Ignored Tags” are long and carefully crafted. How can I back them up just in case Stack Exchange would forget them?
The tag lists in the sidebar and on the Preferences page are text which can be selected and copied just like any paragraph of regular text. So:
You can copy a tag list as text, and paste it to a text document or notebook app on your computer or in the cloud for safekeeping.
To restore a tag list, copy and paste it to the same text field you would write tag names in, and click
(This can also be used for reordering and other modifications of lists, by editing the list in the text document. Tip: The edited list doesn't have to be on just one line.)
