There are of course some cases when I know the translation is very unlikely (especially the diverse books don't get too much recognition here); in those cases I try to get the original versions - at least to know the plot.
But there have been many cases when a given book did get published in my language, but I forgot I was even interested in reading it. So there should be something that would keep track on, for example the TBR list on Goodreads, and notify me when something is available in my preferred language.
