Making the post button open a new tab instead of exiting the current one

My suggestion is: When I press remix or create and make art, every time I have different art that I want to post in separate posts, but when I choose some of them and press post it exits the page and moves to the posting page, my suggestion is that make the post button open a new tab where I post the pictures I choose so that I can have the main page and keep making more images.
