Presenting my first plasmoid: Praedic.
It’s a very simple dictionary targeted at spanish users, or people learning spanish.
It searches the RAE online dictionary, which is the official spanish dictionary (Real Academia Española).
You can get it from kde-look.org, or directly via Plasma’s option “Download New Plasma Widgets“
Usage is very straightforward: Enter a single word and hit enter or press the “Buscar en RAE” (search in RAE) button. There’s a slider on the right side to control the size of the text.
Feedback is welcome!
