Hah, nice! Do you use dead accents? I found it super useful to put all the dead `´^¨° on my altgr-shift-12345 in order to make any accented letter I might want. I use that instead of éèä etc as there's a bunch of variations of it in french, but I don't need them often enough.

This also proved really useful when I started writing in swedish and had quick access to å without having to switch layout.
