I'm just wondering how to know that i added paid dictionaries ( like ABC Chinese-English Comprehensive Dictionary or 21st Century English-Chinese Dictionary ). Cause I want to check the quality of the dictionaries first before I bought it so i try downloaded the demo versions but I found nothing different in my Pleco. So what is the different between the free verisons dict and the paid versions dict? I bought the basic bundle of Pleco ( 29.99$) and quite happy with it! Thanks !
