Can you add the ability to do dictionary lookup quicker and in more languages?

Is your feature request related to a problem? Please describe.
Dictionary lookup is tedious, especially when reading in a foreign language.

Describe the solution you'd like
I would like to be able to lookup words with single click, instead of double clicking and then scrolling to dictionary lookup and then clicking it. I also think a great feature would be the ability to add more dictionaries, like a Spanish to English dictionary. I use eBook readers to read in foreign languages. I simply look up words I don't know. The quicker this is, the better.

Describe alternatives you've considered
The best lookup tool I know is zhongwen. There is no clicking or loading. You hover over a word and it shows you the meaning. Sadly it only works in Chinese.
