Give it the ability to monitor your clipboard
The App would be way cooler if it could monitor the clipboard.
Then I wouldn't have to copy and paste every time I want a line of text translated. Just copy.
Even better, when I play foreign video games, it is sometimes possible to have the game automatically send text to the clipboard.
So, if the translator could monitor the clipboard, the whole process would be entirely automatic.
It has an offline mode, right? So I'm not going to overburden somebody's server with requests.

while you are add it, monitor keyboard strokes as well. As I type in my native tongue, monitor and translate to another language. USeful for writing in another language.
