Unable to change spell check language

I type both dutch and english all the time, but there doesn't seem to be a way to change the language easily, or at all.

In most applications this can be done in the context menu on a text field.

The better solution, which I only ever saw on native Mac applications, is that it detects which language you're typing. Seemingly for every line of text.

Sometimes I'd type a dutch email with an english quote, and it'll figure it out after a while.

This is relatively easy, assuming someone is using words that belong to a known language and are more or less properly written. If half of them are "misspelled", chances are you're using the wrong dictionary. Simply take a few words and look them up in other installed dicts, pick the best match.
