Popup over images in History

Thanks again for the wonderful software!

I figured out that having multiple screenshots in History leads to some usability issue:
- If you have several similar screenshots with small details on them that differs, you need to make the size of images in History bigger to catch the details and paste the right image
- So the size of images in History gets bigger and you can easily miss the needed text lines.
- Decrease the size of images and you return to beginning.

I think it would be really useful not just to expand the size of images in history, but instead have the ability to pop-up zoomed-in images when hovering on them in History.
So then I would have small or medium sized images in History which can be easily seen in details if I hover them with mouse.

And of course settings then must be expanded with new variable:
- Zoom-in on hover (true/false)
- If true — To what maximum sizes should it expand

Also popup is not showing if image can't be zoomed-in since it's smaller then max height and width in History.

I really hope that this feature will be approved.
