Upload already online hosted videos by posting the link and .m2ts format
Vid.Me allows video uploads by just posting the link to a already online video (youtube for example). Having this feature here too would be nice.
Being able to upload .m2ts format would be great too, even if you convert it
There are 3rd party sites out there which already let you import Youtube videos to Twitch. An example would be https://youtube-to-twitch.rootonline.de/
