Arctic

I guess arctic supports uploading media to other places, like catbox.moe, how to choose it as the destination for my uploads, when creating a post?

Also is there a easy way to extract the media (video or image) location from my links. When I upload a video to pixelfed, I usually end up with the link to the post not directly to the video. And I heated from others, that they can't see the video in their clients directly, but have to open the link, and watch in on pixelfed. It would be handy, if Arctic would detect such links, when creating the post, and asks be if I rather like to use the (MP4,…) source in my post. While arctic can handle such links better then most other clients, and watching videos work even if the link isn't directly pointing to the video, I think it would be nice for others to have such an option.
