Floating ADD MEDIA button

Hello,

We create rather long post on our website with many images. It is very time consuming to scroll to the top of the editor to add an image.

I was wondering if any knows of a hack or plugin to make the ADD MEDIA button float with the rest of the WYSIWYG editor to prevent consistently scrolling to the top.

Once you scroll down to much the button moves back to the top. We would like it to remain here https://gyazo.com/a6868ec5e6b352c0dff85bf2047098f7

at all times no matter how far you scroll down
