Heyy sorry for the delay. And thank you for the contribution!

I like the feature of adding a new label dynamically, but I don't know how does the "zoom" and "Copy image path" is supposed to work? I am using MacOS.

For feature 2, it makes image path selectable. It's also possible to right click on image path to choose what to copy.

For feature 3, it's possible to zoom the image at the cursor position with ctrl and middle mouse.

I don't have a Mac machine, I'm not sure if it works well on different OS.
