Why don't you guys make a translation shortcut key for collection?

Hello, dear developer.
Thanks for your app. I have been learning English using this app, which functions are very good for me. Maybe you don’t know there aren’t too many good ways to study English in China, so I like it. But also a little tired of every move and click to collect what I want. I think a shortcut key is a good proposal. Another thing that wearies me out is that I can remove ordinary subtitles meanwhile remain yours with one click. (Because when I opened it, there were two subtitles. So I have to adjust it by setting.) I only had clicked once for a constant episode before, now I have to do it for every single episode. I think it is a huge problem for me and I hope you guys can consider it.
