Components
SteemEditor is an opensource editor made for steemians to make the content creation with ease.
Proposal
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.
Mockups / Examples
Video Preview Mock up
Image Upload Button Mock up
Benefits
Users could save time uploading images somewhere if there is an uploader on the editor.
