Capture region selection - zoom preview for region that won't be the corner of the screenshot


It would be great if it would somehow be possible to magnify not only at the corner, but somehow on the borders, too.
Sometimes one wants to make a screenshot of an object that isn't rectangular and therefore the more interesting point to be magnified would be a border instead of a corner - it would be great if the pixels at each border would be magnified on the outside of the selected area as seen in the attachment

Maybe it should be possible to use the arrow-keys as a toggle since it would need some space and is only necessary in some cases.

Okay, if I got that correctly you would like to be able to have a zoom view of an area on the screen that is not near the mousecursor (i.e. the corner of the screenshot region)... good point, but really challenging to find a good implementation for this problem that is actually usable...

Even if we implemented the possibility to stretch the zoom preview to the width of the full screen, it would still just display maybe 10% of the actual screen width, because it is enlarged by a factor of 10 (currently not sure if that's the actual factor we are using for the zoom).

Another idea is to allow the user to move the zoom preview circle along the dashed green crosshair lines with the keyboard, but this is probably too confusing to use.

As a workaround for now, it is probably best to capture a larger area than you actually need, a few pixels extra on each side - then open the screenshot in the image editor and use the [crop tool](, which does not zoom but allows better control of the rectangle.

Sometime in the future, we are going to have a zoom feature in the editor, which will make pixel perfect cropping very easy. I assume that it will be easier and faster to do the fine-tuning in the editor then, instead of having to interact with the zoom preview while selecting the area to be captured... what do you think?

Best regards,
