I noticed that this ability to use Lookupper to look up words from within its own pop-up windows was lost in the last or one of the latest releases. This function was especially great to have when some word from the "Definition" field was unknown or when the "Dictionary form" slightly varied from the original word (for instance a conjugated verb), in order to get fine-tuned definitions from dictionaries. I really hope this feature comes back in future releases.
