Graphic Novel Screen Translator

Instructions are unclear. It says to "draw a box" around the text you want translated? What does this mean? It doesn't matter if I click the extension and drawing a square around the image/text, highlighting it, or whatever it doesn't work. I've tried clicking the text and then the extension, the text then the extension, but nothing works.

Works as advertised. I wish you could make capture button semi-permanent. Its quite tiresome to always click the extension icon and then press the capture button. I also wish the white box isn't that large or can be customized. The texts are small but the white box is large.
