I did too create my own keyboard layout based on us-intl layout because the local (fi/sv) native keyboard is pretty bad. I took bit more liberties with the layout to be more of a compromise (;:<> were moved around to make space for öä), but overall I'm really happy with the result and recommend better keyboard layouts to any non-US developers/power-users.

Note how all of ~[]{}\$@| are only accessible with altgr.
