fyi: FCPX has released a new version and stopped direct uploading from the app to YouTube. So I think many people are looking for alternatives. So maybe good for this app...

Feature request: Hot folder
I would love to connect the YouTube upload to a hot folder. So I can render the fcpx movie to a folder and starts automatic uploading.

Feature request: WeTransfer
WeTransfer has already a great menu bar option. But how easy would it be to use your shortcuts (or the hot folder) to upload my file to WeTransfer.
