SUMMARY
This is a feature request. I was cropping a load of pictures, and wanted all of the crops to be the same aspect ratio. Specifically, I wanted to drag an arbitrary rectangle for the first image, then lock in that aspect ratio (not the exact number of pixels, but the aspect ratio) for use as a crop rectangle for the subsequent pictures (which I would reach by using the left and right arrows in Gwenview). I hoped, but failed, to find a suitable option for this in the aspect ratio drop-down.

STEPS TO REPRODUCE
1. Open an image in Gwenview
2. Make sure Show Editing Tools is enabled
3. Click Crop
4. Make sure aspect ratio is currently blank
5. Adjust the crop rectangle to an arbitrary size
6. Look in the aspect ratio drop-down for an option called "Current crop rectangle" or "Lock current aspect ratio" or similar

OBSERVED RESULT
No such option found.

EXPECTED RESULT
Such an option found.

ADDITIONAL INFORMATION
I found a workaround, which was to manually type in the current size of the crop rectangle as a ratio, so e.g. if width was 527 pixels and height was 215 pixels, I could type in an aspect ratio of 527:215 and that would lock it in as desired. But I was just hoping for something with just one or two clicks!
