Really satisfied for now. Translations provided at a "double click".

Suggestion for developers: I would like the overlying button that shows when you select a piece of text would display at the top of the selected text instead of at the bottom. This would improve reading as sometimes you just select a fragment of text but with no intention to translate it but just continue reading. The overlying button shows up under the selected line and difficult further reading until you click anywhere to deselect making the button disappear. I think if this button showed up at the top would be less bothering :)
Can you consider implementing the position of the button?

EDIT:
Even though this could be not very convenient if you select many lines (normally from upside down) as you would need to scroll up to see the button. Not sure if is a better placement or not.
