The best but separated

I really love all the Longman dictionaries that I use (Advanced American, Phrasal Verbs, Idioms and Activator). I think they are the best on the market.

The only problem is that I always have to switch between them. It would be much more handily to have one Longman dictionary application and pluggable dictionaries designed as in-app purchases (like in Lingvo). It would undoubtedly be 5 stars.
