Have you ever been in the situation where you had to add [a few] translations on a hook_update instead of importing them from a .po file?
It happened to me several times where I wanted them to be added as part of the database updates, so I found out I could do it using _locale_import_one_string_db().
In the project I am currently working on, we can say that features is almost a prohibited word and every time we need a new field on a content type, we have to add it programmatically through a database update.
Transform any exposed textfield filter of a webform submissions view into multiple drop-down list.
