I always forget the share feature on #Android does more than just share things with others through messaging apps. Want to translate Japanese text? Send it to your #Jisho dictionary app. Want to open a URL? Send it to Firefox. Need to send files using #LocalSend? Send the files to the LocalSend app and send to your other device from there. Need a barcode with some text? Send it to Binary Eye.
It's so useful, but also so hidden I just forget it exists.
