BlendRef is a blender addon for images and videos references managing in the viewport while sculpting, animating or modeling. The image part is similar to BeeRef or PureRef apps but, in blender! No need to put a forced app over your viewport, it's part of it. No need to click on the app to zoom or move a image, you don't leave Blender interface. The video part is very efficient for animation references. You can loop and slow down any segment!
