This is super useful to me. I no longer have to go and put my files into some random site. I just click on the extension, and BAM! Very useful.
awesome
First off, I built this plugin to replace one I loved, but is no longer supported nor offered as a chrome extension. The author discontinued it and so I built my own to replace it. Of course I would give it five stars, but honestly, I love this plugin for what I need, and it is exactly what I need and want.
