Color labeling images in Thumbnail view

[human_robot]

Today I found myself in a situation where I wanted to right click on images in 300x200 Thumbnail view and assign them a color label. I think this would be a nice addition to XYplorer for people who work mostly with images like myself as I need to see what's in the image to label it.

Or is there a keyboard shortcut for this?

There's a Labels toolbar button?
