Nice tool but... Rated 4 out of 5 stars
Very nice and useful but you must provide an option for temporary disable (with CTRL) the zoom feature.
In fact on devianART is impossible with your ad-don drag and drop an image for send it in the favorites folder.
Since version 1.2 has swapped LMB with RMB, I believe this issue should be gone. I couldn't reproduce your issue with v1.1
