Been using PureRef for a while so stumbling across this for Blender is very handy for me. Doesn't work exactly the same as PureRef (can't just copy/paste images from clipboard or grab them directly, need to do extra steps beforehand) and also wish the images scaled with the 3d viewport (resizing it can cause images to be hidden from view). Aside from that, it gets the job done.
Very useful but it shows the image in every window, can't it be deactivated and activated only in specific windows?
Doesnt work in blender 4.4.3
