Feature description

Finnish keyboard layout

Why do you want this feature?

It would be nice to be able to select my own language

Additional information

I have created this feature on my own fork while playing around, might as well bring it here. I'll wait until the "needs triage" label gets removed and then create the PR.

The finnish layout is exactly the same as the swedish one, so i don't know... maybe not the most fancy change.

The finnish layout is exactly the same as the swedish one, so i don't know... maybe not the most fancy change.

Any advantage of adding them as separate layouts?

[j0h-dev]

Most likely no. What I've noticed is that finnish and swedish keyboard layouts have the ever slightest difference if any in other phone keyboard apps, on top of that they are keys that are (almost) never used.

The implementation can just point to the swedish layout file.
