SteemEditor is an opensource editor made for steemians to make the content creation with ease.
I am suggesting that you add a image upload button or drag and drop image function so user can upload their photo from their pc instead of uploading their images somewhere. I have also noticed that your editor does not preview the video fromm youtube. It only shows the link of the video.

Users could save time uploading images somewhere if there is an uploader on the editor.
