Merge branch 'master' into next

Merge branch 'master' into next

Merge remote branch 'operhiem1/comments' into next
Merge remote branch 'operhiem1/mergesfs' into next

longer being updated.
Update default bookmark editions.
Add missing Enzo's Index short description.
Make the entropy warning much clearer.
Add CSS id based on l10n key to menu items.
