there is not a single word that i can use to replace "both" that match correct for both variables
i can use "beide/beides/beiden" as DISPLAY_BOTH variable but this look ugly
but because it is at the backend i can use what ever i wish
and at Frontend Customer dont see this variables anyway, because it is only at the backend on the configuration page
i think it is still better to split it into different variables, than i can use different variables for tax and display
but there is no pressure to do this immediately,
just a hint, because at the actual German language file there is this:
DISPLAY_BOTH="exkl. und inkl. MwSt."
and this is definitely wrong at pagnation both
Kind Regards
