Plain Polish layout is much better and much more „European” than this thing. You can input all the accented letters from all over the Europe (not only letters from Polish alphabet) using combining strokes. For example, ä is "Alt+[ a". In addition to that there's assortment of math/greek characters, many punctuation characters (incl. full set of all the various quotes and arrows, which is handy) and even some Latin ligatures. The single exception is T-comma (used in Romanian), LATIN {CAPITAL,SMALL} LETTER T WITH COMMA BELOW, which AFAIK is impossible to input.
