The preference "Choose your search interface" has two options: "Special:Search" and "Special:MediaSearch". This is a bit too technical because it assumes that the user knows these internal canonical names.
I suggest changing them to something more meaningful and translatable, for example:
- Default general search (Special:Search)
- Search for media files (Special:MediaSearch)
I also recommend changing another two messages that mention "Special:Search" to this:
- Looking for [[Special:Search]]? -> Looking for [[Special:Search|the usual search page]]?
- Switch to [[Special:Search]] -> Switch to [[Special:Search|the usual search page]]
Technically, it's a trivial change in en.json, but I'm creating a task so that designers and product managers can take a look. Perhaps there was a reason for these technical names that I'm not aware of.
