This workflow lets you upload selected files to Cloudup.
If you don't have a Cloudup account, I can highly recommend it if you want to share files with other people very fast. It's owned by Automattic (the company that also owns WordPress.com) and is free to use! You can upload a maximum of 1000 files with a max. filesize of 200mb. It currently is invite only, but you can register with this link (I think, haven't tested this).
You have three options:
Download
Github
Ideas and questions are very welcome .
