I'm curious to see how it deals with dual languages - ie. not switching between them, but using two languages in the same sentence like the google keyboard supports out of the box.

my biggest issue is that i make up a lot of words as i type and the google dictionary for icelandic is .. well it can never be fully complete because of the way the language works, so dictionary words are always a mess.

> because of the way the language works

What's the problem of Icelandic? Is it because you stick words together like in Danish or German?

They have a multilingual input mode that also works with swipe input! I've tried it briefly with Swedish/English on a Swedish keyboard and it switched between languages in the same sentence in a way that made sense to me, but I had to download a separate dictionary.
