    I have no idea what you are trying to say here. (Maybe your keyboard
    looks different from those I have used...)

    I.e. four levels. Dividing it into two groups of two levels is just
    a play with words.

    If you were serious about "two groups with two levels each", then please
    remove the notion of a third level. Or just merge group 1 and group 2
    into plainly four levels. (Of course leaving the layout to national
    standards; as well as vendors.)

    A "second group" (or third group, or whatever) with a jumble of characters
    with no mnemonic connection to what is on the (group 1) level 1 and level 2
    (for each keyboard layout) is not helpful. For rarely used characters where
    one has no mnemonic connection to the (group 1) levels 1/2 layout, then it
    is probably better to use a character picker applet of some sort, rather
    than this "common second group". Note that most keytops only get a single
    character printed on it, in some cases two characters. I don't expect that
    to change much (for aesthetic reasons, leaving open for keyboard layout
    changes, ...).
